Go animation return function

Questions
#1

Hello all.

Last parameter in go.animation it callback function. In my project sometimes it callback function not call. I think it because animation not change position object. I think right? It happenend when GO start next animation very fast and previous animation not finished. May be you know good method resolve problem.

#2

The callback function will only be called if the animation is allowed to finish before you trigger a new animation. An animation that is cancelled (go.cancel_animation()) or replaced by a new animation (go.animate()) will not trigger the callback. And obviously an animation that has a playback of go.PLAYBACK_LOOP_* will never finish and invoke the callback function either.

Thank you.

I have fast change incoming messages for animation parameters and go.animation() - replaced and not finished. I think about change logic, but it may be problem.

#4

I have ran into similar problems at a few occasions where I’ve had multiple animations running on top of each other. Try checking for that.

Yeah I have same.

Logic example:
Every 2-5 sec recieve incoming message, after receive - start animation. If previous animation not finished, next logic not working :frowning:

function y_done(self, url, property)		
	local target_x = 13
	for i=1,10 do							
		if i < 10 then			
			go.animate("/psychoState/psychoStateBarSingle"..tostring(i), "position.x", go.PLAYBACK_ONCE_FORWARD, target_x, go.EASING_INOUTBACK, 1, 0)																			
		else
			go.animate("/psychoState/psychoStateBarSingle"..tostring(i), "position.x", go.PLAYBACK_ONCE_FORWARD, target_x, go.EASING_INOUTBACK, 1, 0, x_done)			
		end	
		go.animate("/psychoState/psychoStateBarSingleEmpty"..tostring(i), "position.x", go.PLAYBACK_ONCE_FORWARD, target_x, go.EASING_INOUTBACK, 1, 0)		
	end			
end	

function x_done(self, url, property)						
--something code
end

function on_message(self, message_id, message, sender)
if message_id == hash("change_state") then
		self.newChange = true		
		if type(message.stateParamsChange) == "table" then			
			self.stateParamsChange[#self.stateParamsChange+1] = message.stateParamsChange
		else
			self.stateParamsChange = {}
		end
       go.animate("/psychoState/psychoPortraitState", "position.y", go.PLAYBACK_ONCE_FORWARD, 186, go.EASING_INOUTBACK, 0.5, 0, y_done)
	end
end

Animation in on_mesage function work good(it ended first) and y_done function ended everytime, but animation in x_done function sometimes not ended and x_done not executed :frowning:
