This is my own little ver of spritecontrol, but obviously I've missed something (only tiled bkg shows). The "Local..." is for a pre-processor *I'm planning* to make so wrong var-names is still a possible cause (but I've tried to check). The images "boxes_r" and "boxes_a" are not the problem... "boxes_a" represents alpha-values (per pixel) of the image "boxes_r" which is just 4x4 solid color squares... Frame 0,0,first box is what should be showing at MouseX,MouseY in this example. The prog gets & frees texture each time dealing with it (in case that is better somehow)... I also made a ver that stored it in s\tex but that didn't work either.
The variable names are short but do make sense: xfs (x-frames[count]) yfs (y-frames[count]). xf (x-frame) etc...
