    [AS3] Arrgghhh Movement

    hey, I am new to AS3, and i am trying to get the character to move (yh i know i am a noob), ive got the character to move in all four directions using the arrow keys but i want him to play a animation while his walking for example when i press the right arrow key, he moves to the right while doing a walking animation...currently when he moves he stops at the start of the walking animation frame

    PHP Code:
    package code 

        
    import flash.display.MovieClip
        
    import flash.events.Event

    Make the walking animation into a movieclip and put it on the stand_forward keyframe

    stand_forward mc isn't "animated"! It contains only one image, what do you expect it to do?

    Add in the rest of the gif frames you have there

    im not sure what you mean, sorry...within the terrymc, there is two positions, the first one is called stand and the second stand_forward....if you double-click into any of them movieclips placed in the keyframe, there will be a animation within that mc

    ah looks like I missed it somehow....

    Anyway, replace all
    player_mc.gotoAndStop("stand_forward");

    with

    Code:
    if(player_mc.currentFrame!="stand_forward")
    				{
    					player_mc.gotoAndStop("stand_forward");
    				}

    ive tried that...now ive got a new problem, the code seems to be generating a error

    #1176: Comparison between a value with static type String and a possibly unrelated type int.

    is there a better way of doing what i want?, as this way to me seems problematic.

    Code:
    // Move up, down, left, or right
    // if(left is true and right is not true)
    if (left) {
    	player_mc.x-=speed;
    	player_mc.scaleX=-1;
    	if (player_mc.currentLabel!="stand_forward") {
    		player_mc.gotoAndStop("stand_forward");
    	}
    }
    // if(right is true and left is not true)
    if (right) {
    	player_mc.x+=speed;
    	player_mc.scaleX=1;

    it works!, thank you soooo much!! ...back to my other point, is there a easier way of implementing this...also how would i go around making a double key press feature e.g. the player presses right arrow twice and the character runs

    would it be more better to use a timer?, e.g. you the user presses the right key and the timer checks to see if the key is pressed within say 2 seconds or sumthing, if this condition is true then the player runs...thank you yet again dawsonk, however when i press the right key, then stop and then press the right key, the player is still running
