what is the problem here?

how do i replace the sprite by a frame when the sprite reaches or passes a certain coordinate, (i tried this)

should work..

Is your animation set to speed 0?

LittleStain should it be?

If it's not set to 0 the animation will just start playing from frame 3 to the end, unless its on loop, then it will play endlessly..

I'm not sure what you are trying to achieve, so I don't know if it should be..

the event also fires every tick while x<=234 if you dont add 'system-trigger once'

LittleStain

fldr

how would you guys do to replace a sprite animation with 5 frames by 1 frame of that same sprite, this while the sprites position is x<=234?

Make a new animation with only the one frame and switch to that or set animationspeed to zero and frame to three..

i think i would add an extra animation with this one sprite and make one event like yours (but not set frame, use set animation) together with 'system-trigger once'

other method could be to make an event, 'set frame to 3' and 'set animation speed 0' and 'system-trigger once'

edit: little stain is always some seconds faster then me ^^
