Question by Clopay · Aug 18, 2012 at 06:09 PM · 2djavascriptspritessprite animation

Sprite Animation - Oneshot

Hey all,

Thought I'd hit you with another question about sprite animation. I've got some sprite sheets for my character in a 2.5D game for which I've animated with success up to this point (using Javascript). I've got an idle, run & a jump animation for both facing left & right. They are all continuous loop animations, which becomes problematic for the jump animation. I'd like the jump to be a oneshot - meaning it plays through once and doesn't loop. Once I figure that out, I'd like to get it to stop on the last frame until told to do otherwise (player touches the ground & sprite sheet changes, etc.). So here's what I've got for the loop animation:

 function aniSprite (columnSize, rowSize, startFrame, endFrame, framesPerSecond)
 {
     var index : int = Time.time * framesPerSecond;            //Calculate the index based on FPS
     //index = index % (endFrame - startFrame) + startFrame;    //Repeats the animation, based on the total amount of frames and where the starting frame is
     index = index % (endFrame - startFrame) + startFrame;
     
     var size = Vector2 (1.0 / columnSize, 1.0 / rowSize);    //Establishes X/Y coordinate values for texture scale
     
     var u : int = index % columnSize;                        //Divide into horizontal index
     var v : int = index / columnSize;                        //Divide into vertical index
     var offset = Vector2 (u * size.x, (1.0 - size.y) - (v * size.y));    //Establish texture offset value
     
     renderer.material.mainTextureOffset = offset;            //Applies offset value to texture
     renderer.material.mainTextureScale     = size;                //Applies scale value to texture
 }

So like I said, I'd like to try and modify this so instead of looping, it's just a oneshot & stays on the last frame (which would be endFrame). If anyone would be able to point me in the right direction, that'd be much appreciated!

Thanks, -Clopay
