Animation problem to do with the update or GetKey function? (C#) {SOLVED}

I'm having a problem to do with my animation restarting every time the 'W' key is pressed, i want the animation to play just once when i hold down the 'W' key yet its constantly restarting instead - is this because i have my code within an update function?

here is my code btw

Code (CSharp):

1. if (Input.GetKey (KeyCode.W)) {
2.                 Debug.Log ("jump should occur");
3.                 playerAnimator.SetBool ("startjumping", true);

if not then in there any way of my fixing this?

thanks in advance

 

It depends on your state machine. Can you post a screen shot of your animator component showing states and transitions? If your transition that depends on 'startJumping' comes from the 'Any State' block, then I can see this happening.

Also something to check: is there anything in your script that will reset the 'startJumping' bool to false? If there isn't, then your controller will keep it at true forever after pressing 'w' the first time. If you don't want to do this, you can use a trigger instead. Triggers will automatically reset when used as a transition condition.

You might also want to double check your transition back to the previous state to make sure it only returns when you want it to, most likely when the character hits the ground again.

 

Are you starting it in an update method, if so call a function in start and have the function call itself, or see if the animation is playing.

 

i am currently using an Any State block for start jumping, what do you recommend i do instead?

i have a line in my script that sets it to false again but I'm not sure if thats another thing causing this problem

Code (CSharp):

1. if (Input.GetKey (KeyCode.W)) {
2.                 Debug.Log ("jump should occur");
3.                 playerAnimator.SetBool ("startjumping", true);
4.             }
5.  
6.             else
7.             playerAnimator.SetBool ("startjumping", false);
8.         }

i tried not to use triggers as this is actually for a side scrolling game I'm working on, this is the character animation

 

hey, just thought i'd state that i think the problem is with the character controller i was using as an example, ive written out a different script for the controller and it all works perfectly fine now

The script i was using was from here http://wiki.unity3d.com/index.php?title=FPSWalkerEnhanced

thank you for all the help anyways, it seems my problem is fixed now

 

The problem is that you're using Input.GetKey, which returns true on every frame the button is held down.

GetKeyDown only returns true on the frame the key is pressed, so that should fix things. Nice to know for future reference even if you worked around the problem in a different way this time

 

ahh thank you so much, i will definitely remember that for the future!
