Scrolling background performance

totebo

I'm using textured shapes for a scrolling background. There is a 100ms pause each time I run the code below, which happens in game when I want to load new background blocks. Could I use meshes, or something else, to reduce this delay?

self.current_background_id = self.current_background_id + 1   local texture_current_bg = Texture.new("gfx_tiled/bg"..self.current_background_id..".png", true, {wrap = Texture.REPEAT}) local texture_width = texture_current_bg:getWidth() local minimum_width = application:getLogicalWidth()*2 local minimum_repeats = math.toint((minimum_width/texture_width)+3) local w = texture_width*minimum_repeats local h = texture_current_bg:getHeight() local shape_bg = Shape.new() shape_bg:setFillStyle(Shape.TEXTURE, texture_current_bg) shape_bg:beginPath() shape_bg:moveTo(0,0) shape_bg:lineTo(w, 0) shape_bg:lineTo(w, -h) shape_bg:lineTo(0, -h) shape_bg:lineTo(0, 0) shape_bg:endPath()

I believe that the delay is caused by actual texture loading (file io, decompression, and upload to GPU). Gideros still miss async texture load...

That sounds likely. I'll try to preload them to see if that works better.
