I have the same problem if you know how to fix it can you help me please.
This works for version 10.1 where the color scale was in 0 to 255. In later versions, the setColor scale is from 0 to 1. So if you run with an alpha value of 1 on a scale of 0 to 255 the visibility would be so low that you can not see any of the objects. The simple solution for this, is to use the 255 scale when setting your colors. Preferably just just create and test the game using version 10.1
