Lua Command imagealpha



  • id
  • alpha


Changes opacity (0.0 transparent - 1.0 opqaue) of an image.

Note: Images with a very low alpha value (below 0.0001) are not rendered anymore. This allows you to hide images efficiently by setting their alpha value to 0. Note however that there is still a small performance impact even if the image is not rendered. If you are sure that you will not need an image anymore you should remove it with freeimage!

Sample 1: Creating an image and changing its opacity
local id=image("gfx/sprites/flare2.bmp",0,0,2)
