Using Camera::Pick to make a model do stuff.

Recommended Posts

Hi I went through the Object script tutorials and I've gotten that crate model to rotate.

 

I've also tested out the Pick example for the Camera class.

 

Now my question how do I make a Camera object that I placed in the editor to do a "Pick" on the crate model then have that model rotate (and maybe even play a sound)?

Inspired from FPSPlayer.lua

 


function Script:UpdateWorld()

...

if window:KeyHit(Key.E) then

local p0 = self.camera:GetPosition(true)
local p1 = Transform:Point(0,0,self.useDistance,self.camera,nil)
if self.entity.world:Pick(p0,p1, pickInfo, 0, true) then
		 if self.entity:GetType() = "crate" then
				 self.entity:SetOmega(10,10,10)
		 end
	 end
end
...

end

 

For sound commands you cna dig AI ro FPSPlayer lua scripts.

So where should I attach such a script?

 

Also how do I make a script that can reference the camera I've placed using the editor than in a script file? I need some help in reconciling the two possible ways to make a camera in the engine either by scripting it or using the editor.

The script above like you can see is on the UpdateWorld().

 

Inside your script just declare an empty entity :

Script.myCamera = nil -- entity

 

The word "--entity" will make some empty field in the script panel where you can drag and drop the camera.

To use it in your functions just use it like that :

self.myCamera:SetPosition(0,0,0,false)

 

You would recommend you to ask Rick for some learning course on Lua and LE3 as he gives courses for beginners.
