Rotation Limit expression

Hi all. A quick question (hopefully). Can someone advise please on a basic expression to limit the rotation of an object when it is turned manually. For example, so it can only move between 0 and 360 and no more back and forth?

Thanks in advance or any help!

You can use the () Math.max and Math.min () functions to keep the value in a given range.  Keep in mind that it will not limit the fundamental value of expression before, only the final value is applied to the rotation.  The object will stop turning when it reaches the upper or lower limit, but the value you provide as input will not itself forced, if that's what you hope.  If you crank well beyond a limit, so you can crank it all the way back to the usable range or reset the numeric value, as if a dimmer turned even after that the light was to its brightness max and inversion it haven't started dimming again until you have cancelled all these additional revolutions.

This is the expression:

minValue = 0;

maxValue = 360;

Math.Max (minValue, Math.min (maxValue, value))

  • Outlook express 6.0 size limit of 2 GB can not open

    Hello, can anyone suggest a way I can open my outlook express 6.0 file Inbox that got compacted and now can not be imported in OE6 due to its size, if I could open it somehow I could then delete unwanted emails etc and then distribute the others in different subfolders so the inbow reached never this size again (which was approximately 5600 emails) , I want a free way to do this and am very disappointed that microsoft cant help me once reach the limit of the CAP? who would have thought that? I found a 3rd party software program (stellar phoenix outlook recovery) who can open it and I see that they ae here but it's a demo and I can't access or delete without registering. I think it of ridiculous and feel microsoft should provide a method without me palming off to third-party sites for a problem that their system has actually created... can anyone offer some constructive advise please?

    @Vyktor:

    I have a free solution below, but you will lose all your messages saved in sent items. If you don't want to lose them, then you must rename the Sent Items.dbx Envoy Itemsold.dbx instead of delete it and then buy the software.

    Spend most of your messages out of the Inbox, and then create new folders to Outbox and sent items.

    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.

    In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.

    With OE closed, find the DBX files for the items in the Outbox and sent and delete them.  New ones will be created automatically when you open OE.

    After you're done, followed by compacting your folders manually while working * off * and do it often.

    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.

    General precautions for Outlook Express:

    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

    Information on the maximum size of the .dbx files that are used by Outlook Express:

    Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the CPUs, slows down sending and receiving and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for the loss of messages. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:

    Note that for some AV programs, it may be necessary to uninstall the program and reinstall in custom Mode and uncheck analysis when the option is the result of e-mail messages.

    Compact often as specified above.

    And backup often.

  • Expression to gradually accelerate/decelerate rotation?

    Hello.

    I'm animating a bicycle downhill (from the top of a hill for the same reason). What expression use gradually speeding up the wheels of the bike? And how I gradually slow down the wheels the bicycle reached the same ground?

    Thank you

    Well, you can simply use a handful of keyframes. Unless it is a Super animated complicated with several climbs and descents and exact rotation distance relationship, it would be useless in the development of complex expressions. If I had to do it "right", it must be based on the pulse of rotation, anyway, and who can get complicated if you wish to appear in the acceleration and deceleration. Really, it's one of those things "why bother brooding on code for hours when you can do it in 3 minutes with keyframes".

  • Interactive report - Expression LOV in filter - limit line

    When you create a filter in an interactive report, the "Expression" this LOV of valid values in the data, but it seems to max out at something around 1000 lines. Is - this configurable? Can I work for say 2000 or 2500?

  • Expression to limit tracking data

    Hello

    Y at - it an expression to limit the scope of follow-up data.  In other words, I would take follow-up data and reduce the size, so if I followed my hand and he moves 10 inches upwards or downwards, I can apply to another and move only 3 or 4 inches.

    You can change all the data, also by something like tracking data

    var x = value [0];

    var y = value [1];

    [x * 0.5, y * 0.5]

    (use any scale to use instead of 0.5)

    However, this scales always data around the point [0,0], which is not always what you need.

    If you use link Simple 2D iExpression, scaling can be done with a lot more options and without any programming at all.

  • How to limit the rotation?

    I do a little fake level indicator I want the pointer to rotate according to the movement of the pointer. I have a clip and have attached the code below.
    Things seem to work ok, but I can't limit the movement on the negative side, how to tell +-60 breast and tell if / else statement? I tried to add a separate statement for - 60, and he did the all unusable.

    Thank you

    Try it like this. (I have not tested because I don't have handy Flash, but I think that it should work).

    Whenever you call the function, it must call a variable (I called it needleRotation). Then the function must first check if the variable is out of your limits or 60-60. Finally, if this isn't out of bounds, then the needle turns to the appropriate amount.

    I would like to know if it works. If this isn't the case, I apologize.

  • Is it possible to limit specific expressions in keyframes?

    I am really a beginner when it comes to expressions.

    I currently use an expression of "bounce" on the position of some objects that arrive on the screen setting. However, the next time they change positions, I don't want them to bounce. Whenever a motion tween ends in a static position, the expression of the position to be applied and things will move.

    I want to keyframe the expression so that it worked only when she's on key images that it makes sense to assign.

    amp =. 05;

    FREQ = 1;

    cavity = 7;


    n = 0;

    If (Numkeys > 0)

    {

    n = .index nearestKey (time);

    If (key (n) .time > time)

    {

    n-- ;

    }

    }



    If (n == 0)

    {

    t = 0;

    }

    on the other

    {

    t = time - .time key (n);

    }



    If (n > 0)

    {

    v = velocityAtTime (key (n) .time - thisComp.frameDuration/10);

    value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);

    }

    on the other

    {

    value

    }

    I got this script somewhere online. The only thing I know how to manipulate are the initial values of the GPA, freq, and decay.

    This version will bounce only to the 2nd keyframe:

    amp =. 05;

    FREQ = 1;

    cavity = 7;

    KF = 2; only on the 2nd keyframe

    n = 0;

    If (Numkeys > 0) {}

    n = .index nearestKey (time);

    If (key (n) .time > time) n -;

    If (n == kf) {}

    t = time - .time key (n);

    v = velocityAtTime (key (n) .time - thisComp.frameDuration/10);

  • If is it possible to apply the wiggle expression loop to individual characters in a block of text?

    I'm relatively new to After Effects and text animation. What I was, I was wondering if there is a way to essentially take the effect of a wiggly selector, rotation, which applies to each individual character, and then pass? Also impressive that the expression 'loop wiggle' is, it seems to apply only to the entire text block.

    Selectors of expression work on indexes text and the expression of Dan is not adapted specifically work on text animators. It only returns a uniform value. You have to build a loop around it for each character through the clues. If you really have such a short text, it can be faster and easier for you to understand, to use only the many animations of text because there are letters and limit the influence of each in a single character...

  • Limit on the expansion of network?

    I have 3 AirPort Extreme base stations, 2 are 5th generation and a 3rd generation. I also have an AirPort Express in the mixture. I have a 3rd generation connected to the FiOS router and I consider that it is the "primary" router Initially, it worked. I had 2 Extreme extending by connecting to the 'main' and the Express has been connected to one of the Extreme 2 extension. This morning, an extreme extension 2 has been disconnected. The error was that he was unable to expand the network. I checked the range and it's well within 100 feet of the central station. I checked the network password and that's OK. I unplugged the other extreme, which extends and restarted then that gave the error. This time, he connected very well to the main but when I turned on the other that I had turned off, he started too give the error of not being able to expand the network.

    Yes, is there as a limit to how many base stations can connect to one to extend a network?

    I checked the range and it's well within 100 feet of the central station.

    100 feet is quite far away... even if you have line of sight between the main airport and the airports of their extension. If there are walls on the signal path, get a good signal for extending airport is going to be quite a challenge.

    The golden rule for the placement of an airport that will extend wireless is the place to a point that is about halfway between the airport and the area that needs more wireless coverage.  For example, if you need more wireless coverage has a few rooms at the other end of the House, extending airport would be located in between the main airport and the other end of the House.

    The reason is that the airport expansion "to extend" the quality and the speed of the signal it receives. If it is located too far from the main airport, then it gets a signal low and slow to expand, so there are few vested benefits.

    I had 2 Extreme extending by connecting to the 'main '.

    Understand that.  If all goes well, the two extremes are found as they are at equal distance between the main airport and each Extender... And each extension's closest major airport that it is another extension unit.

    and the Express has been connected to one of the Extreme 2 extension.

    The Express is unable to extend the signal to a device that is already expanding the network. In other words, you can have multiple devices, the expansion of the network, but each extension must connect directly to the main airport... not at another airport that already is the extension of the network.  In your case, the AirPort Express is actually 'join' the network... so it will work for AirPlay or a printer USB remote... but the Express provides no additional wireless signal coverage in this type of installation.

    For the moment... try turning off all the... from the 'main' airport and all other airports.

    Wait a few seconds and then starts the 'main' airport and run a minute or two

    Turn on one of the extreme airport which extend the network and let it run for a minute or two

    Assuming that the AirPort Extreme that works you just turned correctly, turn on the other AirPort Extreme

    Post back your results, and we are going to discuss options for the Express.

  • Expression evaluation limits step

    I'm just trying to understand the point at which the step limits expression is evaluated. I'm trying to define the limits of a test of numerical limit based on an expression. I'm passing the context of the sequence for the LabVIEW code module so that the VI may determine the limits to set the colors of parts of pass/fail indicator and for certain other purposes.

    The problem I have is that it resembles the step limits expression has not been evaluated at the time wherever the context of the sequence is passed to the VI, which means that the calculated limits are not available. Is this correct? If so, does anyone have suggestions as to how I might be able to get around this?

    Thank you.

    Adam

    Hi Adam,.

    The following graph shows the order of execution of the teststand steps.

    I believe that the evaluation of the expression limited on "steps of numerical limit test" occurs during the evaluation of the expression status (so the last part of the stage).

    Another solution would be to create your own custom step type and include a custom "step first substep for your personalized step step" (I think I just broke the world record for most uses of the word 'no' in a sentence )

    However, I think that you've already found the solution more practice/simple/elegant. Yes, Bravo to you!

    Thanks for your time. I hope that gives a little clarification.

  • Problem - edges of digital triggering slows down during the fast rotations

    Hi all. I have problem to understand. I want to measure the pressure with two strain gages on 90 degrees (NI 9237 half bridge II) and I engine with metal plate on it with 52 teeth (gear) to measure on each tooth of the strain. For the rotation, I use NI 9401 digital input.

    I need for example 1000 samples from the first digital edge to the second. (on the metal plate). I try to start trigger. In slow speed (turn around with the hand) of the metal plate, everything is OK. But if I turn around the metal plate digital fast triggers edges slows down. During a cycle on the metal plate on the cost of slow speed me 52 digital edges 1000 sampels by edge (metal plate is with 52 teeth), but rely on fast speed on me 25 edges. This problem is sync of the digital inputs and the analog inputs. I made the example with DAqmx Vi express. I've implemented on digital imput and then count me in each tooth regardless of speed and everything is OK, but when I buid trigger of strain on the edges of quick release rotation speed slows down.

    Can someone help me with this?

    Thanks before.

    So you're collecting samples from 1000 to 10000 samples per second. Which takes 100 Ms. If your triggering edges occur more quickly than the interval of 100 ms, some of them will be missed.  If you run faster than a cycle all 5.2 seconds your gear plate with 52 teeth, some triggers will be produced before the end of the previous data collection.

    What is the fastest speed that you will not sping palte metal?

    I would advise against doing that. Not all the values exactly representable UInt64 Float64 so you will get a rounding error. It depends on what you are doing or not that would be important.

    Digital limit stage does not support 64-bit integers, but the expression function CheckLimits() support them so you could do something like:
