| Summary | 0031725: YYC: Arguments now being passed by-reference introduces unexpected behaviour | ||||
| Description | GML: function destroy_squirrel(squirrel) {
show_debug_message("DESTROYING SQUIRREL "+string(squirrel));
if (global.event_squirrel == squirrel) global.event_squirrel = -1;
show_debug_message("DELETING SQUIRREL "+string(squirrel));
}
function scr_a_bug(){
global.event_squirrel = 0;
destroy_squirrel(global.event_squirrel);
}VM output: DESTROYING SQUIRREL 0 DELETING SQUIRREL 0 YYC output: DESTROYING SQUIRREL 0 DELETING SQUIRREL -1 As you can see, since the global is passed by-ref rather than by-value, YYC experiences seemingly impossible behaviour with argument value not matching what was passed after modifying the original value. | ||||
| Additional Information | I'm not actually sure how this is best approached without reverting the optimization. Happens in 2.2.5 too. | ||||
