Question about hooks

[jrhetf4xb]

A few things came to my mind with hooks but first I want to clarify some things since I've never used them.

What happens with the hooked function? Is it still a valid call even if hooked?
What I mean is this:

hook PauseUnit CustomPauseUnit

function CustomPauseUnit takes unit whatever, boolean toPause returns nothing
    set this = asffsafsa
    set that = afsfasfsa
    // etc.
endfunction

Will it still pause the unit AND do all the stuff in my custom function? If not, if I use PauseUnit within my CustomPauseUnit would there be some kind of recursion that would cause it to fail?

the hook just work to you execute some function when some native/bj run... but don't work if some bj/native use the function to callback...

so yes, it will execute first the PauseUnit then will execute ur function


example of limitation of hook:

function CustomPauseUnit takes unit whichUnit, boolean pause returns nothing
    call BJDebugMsg(GetUnitName(whichUnit))
endfunction

hook PauseUnit CustomPauseUnit

call PauseUnitBJ(true, whichUnit) //the hook don't will run with this function since you can't detected the callback of the function

call PauseUnit(whichUnit, true) //the hook will run with this function since this is the direct function

Hooks in vJass are weak. A better programming language would allow the returned-value t be hooked, as well.

A compiled-hook in vJass turns into some ugly trigger evaluations, as well, instead of faster function-calls. Hooks are trash.
