Player:SetAllowWeaponsInVehicle Problem

[RedXVIII]

The problem with using [URL="http://wiki.garrysmod.com/page/Player/SetAllowWeaponsInVehicle"]Player:SetAllowWeaponsInVehicle[/URL], is that you can't really shoot out of the car without killing yourself, because it just shoots the car, which ends up killing you. Is there a way to fix this? Like maybe edit bullet collision groups, or something? I'd love to get this to work properly.

You need a custom weapon base that handles this.

You can prevent the damage in the EntityTakeDamage hook, but it'd be better if the vehicle itself had a proper physics object that allowed that, like the Jalopy does, or the seats themselves.

After about 30 minutes of looking through pages of the "Next Update" thread, I found what i was looking for:

I already knew this had to be setup by the users, but how would you do this in a weapon base? I have one already made, what do I need to do?

This is the code i added to my Mad Cows Weapons to account for this:

   
   local source = self.Owner:GetShootPos();
   
   if (self.Owner:InVehicle()) then
      // first we trace from where we are to where we are shooting
      local tr1 = {}
      tr1.start 	= self.Owner:GetShootPos();
      tr1.endpos 	= self.Owner:GetShootPos() + (self.Owner:GetAimVector() * (4096 * 8));
      tr1.filter 	= {self.Owner, self.Owner:GetVehicle()};
      
      if (IsValid(self.Owner:GetVehicle())) then
         table.insert(tr1.filter, self.Owner:GetVehicle():GetParent());
      end
      
      local trace1 = util.TraceLine(tr1);
      
      // then we trace from the hitpos of trace1 BACK to where we were shooting from with no vehicle filters
      local tr2 = {}
      tr2.start 	= trace1.HitPos;
      tr2.endpos 	= tr1.start;
      tr2.filter 	= {self.Owner, trace1.Entity};
      local trace2 = util.TraceLine(tr2);
      
      if (IsValid(trace2.Entity)) then
         source = trace2.HitPos - (trace2.Normal * 8);
      end
   end

This is great code, thank you so much.
