having problems thinking of the logic to have animations playing, say w to walk, becauswe of course if you keep w pressed in it will restart at frame 0:

the thing is I have seperate fbx files,one for walk,the other jump,and so on,as I was unable to join fbx files, this works fine, here is the code

+ Code Snippet

//W Key Forwards
		if GetRawKeyState( 87 ) 
			
			Move3DPhysicsCharacterController( objID, 1, -WalkVelocity )
			//SetObjectAnimationFrame(myplayer,GetObjectAnimationName(myplayer,1),0,0)
			deleteobject(myplayer)
			myplayer=CloneObject(mywalkplayer)
			SetObjectImage(myplayer,62,0)
			SetObjectNormalMap(myplayer,63)	
			PlayObjectAnimation( myplayer,GetObjectAnimationName( myplayer,1),0,42,0,0)
			SetObjectAnimationSpeed(  myplayer,60 ) 
		endif

as you see I have to delete myplayer before I clobe it with the correct object+ animations, but how do /I say to just play the animation all the way through! as everytime w is pressed it start at frame 0

I'd recommend implementing a concept of character states. The control input then doesn't affect the character directly, it sets a state. A separate character update then looks at the states and determines how to update the character object.

say you have the character's 'action state' set to 'idle'
You press/hold W which sets the action state to 'moving'
when you detect that the state has changed from idle to moving, you can trigger a loop walk animation
while the state remains moving, you can move the objects position
You release W which sets the state back to idle
when you detect that the state has changed from moving to idle, you can trigger a stop animation and/or loop an idle animation

by abstracting away the resulting update actions from the input controls, you can then also use the same character update process to handle AI NPCs, you can set thier states by an AI update instead of the player's direct inputs, but the character update process doesn't need to know how the states were set.

it seems to get messy though as i need a few animations!, walk,run,jump and idle
I basically need to be shown with some rough code!

#constant walk=1
#constant run=2
#constant idle=3
state=idle:oldState=idle
do
rem check key or button presses and set state here
.
.
.
.
.
.
.
.


Select state
	case walk:
	 	if oldState<>walk //animation has changed
			StopObjectAnimation( objID ) 
			PlayObjectAnimation( objID, animName, starttime, endtime, loop, tweentime ) 
		endif
		oldState=walk	
	endcase
	case run:
		if oldstate<>run
			StopObjectAnimation( objID ) 
			PlayObjectAnimation( objID, animName, starttime, endtime, loop, tweentime ) 
		endif
		oldState=run
	endcase
	case idle:
		if oldState<>idle
			StopObjectAnimation( objID ) 
			PlayObjectAnimation( objID, animName, starttime, endtime, loop, tweentime ) 
		endif
		oldState=idle		
	endcase
endselect

sync()
loop

The above should work well if you set the animations to loop
