AutoHotKey Key Combinations (remap) for key modifiers - keyboard-shortcuts

Question

I want to change the use of Ctrl to Spacebar for three commands in a game but not for everything cause then I can't use space to communicate. The normal commands are Ctrl+q, Ctrl+w, Ctrl+e, Ctrl+r and Control+RButton (right mouse). Right now I'm usng Space::Ctrl, however I have tried different solutions with no result.
[EDIT/]
#MCL Ok. I looked at the forum thread you posted and tried the code below which sorta worked. It sent the keys how I wanted, but each shortcut triggered all shortcuts that followed it. For example space+e triggers space+e, space+r and space.
Also, Spacebar still didn't work. I added the Space::Space later and I can get a text space only by using the Space+(q, w, e or r) shortcuts.

Send {Ctrl up}
Space & w::
Send {Ctrl down}

Found it. I needed to add the returns.
#NoEnv
SendMode Input
#InstallKeybdHook
#UseHook
#IfWinActive ahk_class RiotWindowClass
Space & q::
Send {Ctrl down}
Sleep 30
Send {q down}
Sleep 30
Send {q up}
Sleep 30
Send {Ctrl up}
return
Space & w::
Send {Ctrl down}
Sleep 30
Send {w down}
Sleep 30
Send {w up}
Sleep 30
Send {Ctrl up}
return
Space & e::
Send {Ctrl down}
Sleep 30
Send {e down}
Sleep 30
Send {e up}
Sleep 30
Send {Ctrl up}
return
Space & r::
Send {Ctrl down}
Sleep 30

Regarding : "Space will only work as text and won't work as the shortcut to center camera on your character."
Try using SendMode Play instead of SendMode Input.
SendPlay's biggest advantage is its ability to "play back"
keystrokes and mouse clicks in a broader variety
of games than the other modes.
-- From the documentation for SendPlay.
For further reading about Send mode settings, tradeoffs & abilities, check out the documentation for SendMode .
Regarding : SetKeyDelay
SendMode Input will not be effected by SetKeyDelay:
Note: SendInput ignores SetKeyDelay
because the operating system does not support
a delay in this mode.
-- From the documentation for SendInput
Additional information :
One thing to be aware of when using Custom Combinations (docs) (i.e. using non-modifier keys for hotkey combinations):
when you defined the first Space & otherkey::, the Space key becomes a "prefix key", which means it loses its native function. This necessitated the final hotkey you defined in your example :
Space::
Send {Space}
return
A note of caution : this hotkey (which restores functionality to the prefix key) fires when Space is released. And it will not fire if any other key is pressed between Space down and Space up.
Your script works as expected otherwise in Notepad++ (replacing the Send lines with MsgBox for debugging).
So this is likely an issue with the game picking up AHK's sent space key.
Try debugging by making a simple script which does nothing other than sending Space to the game using different SendModes.
