Walls and friendly fire

[Krapougnak]

Hi,

What files do I need to change to make a wall block friendly fire ?

(i'm using a mod with T2 and T3 walls and my units firing through them look ridiculous)

Thanks for your help.

unit.lua, OnCollisionCheck. if EntityCategoryContains(categories.WALL, other) then return true

Thanks a lot !

I will try this as soon as I get home.

Didn't work... what I'm I doing wrong ?

I put the file in the mod "hook/lua/sim" folder correct ?

Code: Select all

local UnitOld = Unit

Unit = Class(UnitOld) {

    OnCollisionCheck = function(self, other, firingWeapon)

        if EntityCategoryContains(categories.WALL, other) then
   return true

        end
            UnitOld.OnCollisionCheck(self, other, firingWeapon)
    end,
}

Right, that won't work.

If you just want walls to block everything, replace it with:

Code: Select all

local UnitOld = Unit
Unit = Class(UnitOld) {
    OnCollisionCheck = function(self, other, firingWeapon)
        if EntityCategoryContains(categories.WALL, self) then
            return true
        end
        return UnitOld.OnCollisionCheck(self, other, firingWeapon)
    end,
}


Remember to return the value that UnitOld.OnCollisionCheck yields

Oh, it works that way around huh? My bad mate.

It worked !!! Thanks a lot !

Remember to return the value that UnitOld.OnCollisionCheck yields

What do you mean by that ?

I meant there was a difference between the snippet you posted and mine:

Code: Select all

UnitOld.OnCollisionCheck(self, other, firingWeapon)

vs

Code: Select all

return UnitOld.OnCollisionCheck(self, other, firingWeapon)

The return keyword is crucial to ensure everything else doesn't stop colliding

Oh, OK that explains a lot... .

Thanks again for making my playing experience better.
