Unprojecting a mouse and ray casting
by James Terry · in Torque Game Engine · 12/04/2006 (1:38 pm) · 6 replies
I currently have my game set up to use ShapeBase.cc's castRay function to return the object name that it hits first. I was building the parameters to send to it by figuring the x/y positions of each corner of the square I am interacting with in mouse positions, then converting it to world dimensions (which I don't think is working too well)
Is there a way for me to, with a static view of my world, unproject the mouse x/y into world coordinates and then send a rayCast out, I keep getting erroneous data for which object is being hit.

Do you know of a way to convert T2D's onMousedown %worldPosition into the GuiEvent that GameTSCtrl uses. Last time I tried that resource it would give me the same unproject no matter where I clicked on the screen and wasn't too much use.

try reading the whole thing.
there's a lot of good advice in it around how to get it working.

I'll work on it first thing in the morning. I may have been mistaking it for a different resource I tried. Skimming through the code it seems like just what I need.Thanks for the reccomendation

I have one small issue though. I am rotating some of my objects and ContainerRayCast is returning when it hits a bounding box of one of these rotated objects instead of returning when it hits the collision mesh, is there an easy way to change this functionality?

Alright, its all in and working :)I have one small issue though. I am rotating some of my objects and ContainerRayCast is returning when it hits a bounding box of one of these rotated objects instead of returning when it hits the collision mesh, is there an easy way to change this functionality?

try posting the question to the object selection resource - maybe someone who knows the answer is watching the thread.
