Loop Error in AutoHotkey -

i'm trying make script push space every 50ms every time press key. want loop continuously. here code:

loop { ^p:: send, {space} sleep, 50 return } 

assuming want start ctrl+p, have put loop inside hotkey execution body:

^p:: loop {     send, {space}     sleep, 50 } return 

note: it's programming style end hotkeys return, please know return never reached! (never-ending loop)

for activating , deactivating space sending, might want use settimer like:

#persistent active := false  ^p::     if(active)         settimer, sendspace, off     else         settimer, sendspace, 50     active := !active return  sendspace:     send {space} return 

i don't know why it's not working. when press again nothing happens , continues pressing space.

since it's working me, guess cpu/ram blame. i'll quote answer question here: sendinput won't work @ high speed :

looks me autohotkey bug likely, or wrongly sent {space}s because ram can't handle heavy programs enough.

things can think of try:

• buy better computer.

• use setbatchlines, 1ms (in beginning of script), making script sleep 20ms each millisecond , therefore consuming less cpu. might clear autohotkey's mind.

• setkeydelay, 50 might help.

sometimes, pressed down modifier such ctrl or alt, slows down windows drastically. @ least case under windows vista. might wanna rid of ^ (ctrl) , change hotkey plain p:: hotkey, example.

if still no option you, try this:

#persistent active := false  ^p::     settimer, sendspace, 50     hotkey, p, stopsendspace, on return  sendspace:     send {space} return  stopsendspace:     settimer, sendspace, off     hotkey, p, stopsendspace, off return 

this behave above (activation ctrl+p again), deactivation happens p (no ctrl), without overriding default behaviour
