timed sprite animation

deezay

I'm fairly new to this stuff, I have just looked at the animation and timers sample. I was wondering how i could combine these two together to create multiple animations that move independently based on different timers or a certain time after the previous sprite has moved? Any help will be much appreciated.

You can add a timer to the Bird class (inside the Bird:init method):

self.timer = Timer.new(20, 0)   self.timer:addEventListener(Event.TIMER, self.onTimer, self) self.timer:start()

Then, instead of changing the current animation frame inside Bird:onEnterFrame, do it inside the timer event:

function Bird:onTimer() self:removeChild(self.frames[math.floor(self.frame)]) self.frame = self.frame + 0.1 if self.frame >= self.nframes + 1 then self.frame = 1 end self:addChild(self.frames[math.floor(self.frame)]) end

Hope this helps.

ok thanks i did notice a change but just to check is this wt u meant -

Bird = gideros.class(Sprite)     function Bird:init(frameList)   self.frames = {}   for i = 1, #frameList do self.frames[i] = Bitmap.new(TextureRegion.new(Texture.new(frameList[i]))) end   self.nframes = #frameList   -- to find the bounding box we add all childs and then remove them for i = 1, #self.frames do self:addChild(self.frames[i]) end   local width = self:getWidth() local height = self:getHeight()   for i = 1, #self.frames do self:removeChild(self.frames[i]) end     for i = 1, #self.frames do self.frames[i]:setX(-width/2) self.frames[i]:setY(-height/2) end     self.frame = 1 self:addChild(self.frames[1])   self:setX(540) self:setY(math.random(160) + 40)   self.speedy = math.random(-1000,1000)/1000   self:addEventListener(Event.ENTER_FRAME, self.onEnterFrame, self)   self.timer = Timer.new(20, 0) function Bird:onTimer() self:removeChild(self.frames[math.floor(self.frame)]) self.frame = self.frame + 0.1 if self.frame >= self.nframes + 1 then self.frame = 1 end self:addChild(self.frames[math.floor(self.frame)]) end self.timer:addEventListener(Event.TIMER, self.onTimer, self) self.timer:start() end     function Bird:onEnterFrame() self:removeChild(self.frames[math.floor(self.frame)]) self.frame = self.frame + 0.1 if self.frame >= self.nframes + 1 then self.frame = 1 end self:addChild(self.frames[math.floor(self.frame)])   local x = self:getX() local y = self:getY()   if (y > 300) then self.speedy = 2 * self.speedy end if (y < 10) then self.speedy = -2 * self.speedy end     x = x - 3 y = y + self.speedy   if (x < -10) then x = 540 y = (math.random(160) + 40) end print(x, y)   self:setX(x) self:setY(y)   end

This was what I meant

Bird = gideros.class(Sprite)     function Bird:init(frameList)   self.frames = {}   for i = 1, #frameList do self.frames[i] = Bitmap.new(TextureRegion.new(Texture.new(frameList[i]))) end   self.nframes = #frameList   -- to find the bounding box we add all childs and then remove them for i = 1, #self.frames do self:addChild(self.frames[i]) end   local width = self:getWidth() local height = self:getHeight()   for i = 1, #self.frames do self:removeChild(self.frames[i]) end     for i = 1, #self.frames do self.frames[i]:setX(-width/2) self.frames[i]:setY(-height/2) end     self.frame = 1 self:addChild(self.frames[1])   self:setX(540) self:setY(math.random(160) + 40)   self.speedy = math.random(-1000,1000)/1000   self:addEventListener(Event.ENTER_FRAME, self.onEnterFrame, self)   self.timer = Timer.new(20, 0)   self.timer:addEventListener(Event.TIMER, self.onTimer, self) self.timer:start() end   function Bird:onTimer() self:removeChild(self.frames[math.floor(self.frame)]) self.frame = self.frame + 0.1 if self.frame >= self.nframes + 1 then self.frame = 1 end self:addChild(self.frames[math.floor(self.frame)]) end   function Bird:onEnterFrame() local x = self:getX() local y = self:getY()   if (y > 300) then self.speedy = 2 * self.speedy end if (y < 10) then self.speedy = -2 * self.speedy end     x = x - 3 y = y + self.speedy   if (x < -10) then x = 540 y = (math.random(160) + 40) end print(x, y)   self:setX(x) self:setY(y)   end
