Hi,
when I move a sprite with a transition then there appears an artifact.
So if I move a sprite to the left side then on the right side of the sprite there sometimes appears on horizontal line of the next frame.
Here is a code to show you the problem:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | local sprite = require("sprite") display.setStatusBar( display.HiddenStatusBar ) local background = display.newRect(0,0,display.contentWidth,display.contentHeight) background:setFillColor(255,255,255,255) local spriteSheet = sprite.newSpriteSheet("sprite.png",60,60) local spriteSet = sprite.newSpriteSet(spriteSheet,1,2) sprite.add(spriteSet,"test",1,2,2000,1) local object = sprite.newSprite(spriteSet) object:prepare("test") object:play() object.x = 200 object.y = 200 transition.to(object,{x=50,time=1000}) |
This sounds like an openGL rendering artifact where the texture edge can wrap around to the other side of the polygon it's being rendered on. Try adding a 1-2 pixel transparent border around your sprite texture and see if the artifact goes away.
Hi XenonBL,
Thank you this helped, although I now have to set the frame sizes and positions manually.
