auto press space

I'm trying to make an autohotkey script that will automatically press spacebar for me.
unfortunately, the command won't send to the game. anyone knows how to fix this??
btw, I know that I should post it on autohotkey, but noone knows anything about ava there (i've tried already..).
bttw, I have 32-bit, maybe that has something to do with it.
btttw, the solution doesn't HAVE to be an autohotkey script, it can also be like a macro for spacebar or something.

bump :I don't want to do this but i really want someone to help me...

External Input works only with a bypasser and i think none of the 32bit ones working

thanks, so: there is no way at all to auto press space with 32-bit? cause, i once downloaded a macro, and it worked. so external output should work too rght? p.s. i suck at these kind of things :I
