I am new for the GML. I have tried to read the code in Yoyo Brick Breaker Demo. I have see this code in the script "ClearBlock": ... var count = global.hits[# argument0>>5,argument1>>4]-1; ... I have no idea what happened if it use shift operator (>>) for argument0 and argument1, And the # symbol, I have tried to search its meaning in help file but cannot find. May someone know and kindly advise? Thank you.
