so im trying to compile this and i get an error ever time i have tried to use mov instead of movss i cant seem to get my symbol value to move to eax+04 or eax+04 to move to my symbol value but i can get it to move to other varibles like exx or xmmo why wont it got to my symbol? is there a diffrent command i need it to do to make that happen?
because i need to be able to change what is in eax+04 and see whats there too but i cant ( none of this would be necicary if my base pointers did not change ever time i load the game code shift i hate you! but im trying to make a hack where i can change my Y axis but i cant seem to figure it out I suck at assembly but i did figure out it moves i works like
mov Into this, this right ?/ so it moves what ever is on the right into whats on the left?
thanks again and hope for help soon
