sprite flickers

Games
#1

I’ve created a sprite sheet with 125 images using Zwoptex. I’ve also created a coordinate file from within Zwoptex. When I test the project in Corona Game edition, the sprite flickers and jumps to incorrect frames. I think the issue is that the Coordinate file is not being read correctly, but I’m not getting any errors

here is the code I’m using for my main.lua
require (“sprite”);

local zwoptexData = require “pigCord”
local data = zwoptexData.getSpriteSheetData()
local sheet=sprite.newSpriteSheetFromData(“PigSheet.png”,data)
local set=sprite.newSpriteSet(sheet,1,125)
local instance=sprite.newSprite(set)
instance.x=200;
instance.y=200;
instance.yScale=1;
instance.xScale=1;
instance:play();

I can provide the sprite sheet and coordinate file if needed. Is there a most recent example of using Zwoptex and Corona?

Thanks

The sprite also randomly cuts off the lower half of the image. The particular frame changes and appears to be random. [import]uid: 6893 topic_id: 3725 reply_id: 11364[/import]

i believe there’s a bug in the reading of the size from spritesheetdata.

Thanks jmp909.
I’ve found the source of the issue and hopefully it will help someone else down the road.
I’m using sprite.xScale=-1 to flip the sprite horizontally. This introduces a little flicker at the end of the sequence which is not there when the sprite is not flipped.
The second issue was with my sprite sheets. The images I was using to create my sprite sheets were labeled image1.png…image125.png. They should be image001.png…image125.png so that they sort correctly by name.
