[HELP] How do i overwrite functions without loop?

[gamerpaddy]

Hey, how can i do that?

An example.. i want to clamp SetPos to Max map size..
My code is:
[LUA]
local RSetPos = _R.Entity.SetPos
_R.Entity.SetPos = function(pos)
local MinMax = 16384

pos.x = clamp(pos.x,-MinMax,MinMax)
pos.y = clamp(pos.y,-MinMax,MinMax)
pos.z = clamp(pos.z,-MinMax,MinMax)
RSetPos(pos)

end
[/LUA]

but it ends in an Infite loop.. SetPos call RSetPos call SetPos call RSetPos.............

How do i do that?

It would be usefull, to clamp values that crash garrysmod (force, physic, position, angles etc.)

Your code is good as far as I can tell, but if it's ran more than once it can become unstable.

Change:

local RSetPos = _R.Entity.SetPos

To:

RSetPos = RSetPos or _R.Entity.SetPos

This ensures that the old function does not get 'lost'.

Yeah, also your prototype is wrong, it should be function(self, pos)

Your concept isn't going to work since VPhysics is calling functions from the engine, not the ones in the Lua state.
