Alienhead Posted Thursday at 11:43 AM Share Posted Thursday at 11:43 AM How to completely remove an entity that uses the same variable in the same routine. I have two variables that hold references to two weapon entities the player uses. Scenario: Player changes weapons but nulling the variable holders for the previous weapons dont work because the new weapons fill in the varaible preventing it from being deleted. -- drop old weps self.weplefthand = nil self.weprighthand = nil collectgarbage() self.weplefthand = NewWepToHold1 self.weprighthand = NewWepToHold2 Quote I'm only happy when I'm coding, I'm only coding when I'm happy.

It should not prevent it at all. Are you sure there are no other pointers exist to those weapons? Example how same reusing of var deletes prev entity without other references to it: local displays = GetDisplays() local window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[1], WINDOW_CENTER | WINDOW_TITLEBAR) local framebuffer = CreateFramebuffer(window) local world = CreateWorld() -- Create a camera local camera = CreateCamera(world) camera:SetClearColor(0.125) camera:SetFov(70) camera:Move(0, 2, -8) -- Create light local light = CreateBoxLight(world) light:SetRotation(45, 35, 0) light:SetRange(-10, 10) local box = CreateBox(world) box:SetPosition(1, 1, 1) -- Main loop while window:Closed() == false and window:KeyHit(KEY_ESCAPE) == false do collectgarbage() world:Update() world:Render(framebuffer) if (window:KeyHit(KEY_SPACE)) then box = CreateBox(world) end end Quote Link to comment Share on other sites More sharing options...

You can call SetHidden() to hide them, if nothing else works. In Leadwerks, stuff like this could cause invalid pointer errors, which are impossible to detect and cause random memory overwrite.
