Can you tell me how to use it ??

i use pickline to get the object -> %obj

then use %obj.castCollision ???

I want to get the point of collision of the "pickline" and the obj picked~

Maybe that'll help. It will return your point of collision as a vector.

I was looking at this today myself as I need a line of sight test to see if i can shoot an enemy. castCollision() is our only tool for doing this. I haven't tested this yet, but i believe that you could create a temporary dummy SceneObject with a small collision shape with castCollision() to fake a line collision test. It's a horrible waste of resources... as all you need is an instantaneous test.... but it would work.

I asked about something like this almost a year ago here.

The problem still persists, there is no elegant way of doing things as line-of-sight detection against tiles in a tile layer.

Edit: And this was my post on the suggestion board.
I've been out of touch with T2D... TGB, or whatever you call it these days. Anyone feel free to mention if this has been worked on since last September.
