How to actually make raycast hit colliders it s starting from?
Hi everyone!
I have a very good knowledge of how raycasts work, with the layers and stuff, but today I have a problem that apparently nobody has, or at least they are overwhelmed by the opposite problem so I couldn't find a solution:
I am making kind of an RTS with a non-rotating isometric camera, thus, when units go behind walls, I want to render them in transparency, like this:
So as you can see, it works fine by now, the only issue is that to do this, I do a capsuleCast from my character to the camera, but as I can go inside buildings, I am currently forced to use a mesh collider on my building or manually place box colliders on all my walls to detect them when I'm inside. Primarily I wanted to simply use a box collider all around the building to optimize the collisions, but of course, if I am inside, the capsuleCast doesn't detect the collision.
Here's a little illustration: 
So my question is this: is there a way to actually detect colliders the raycast is done from, please? (I saw something about changing a "Raycast collision inside" parameter or so in Edit->Preferences->Physics, but I couldn't find the parameter)
Also, I'm using Unity 5.2
Thanks a lot for your time!
Can't you do the CapsuleCast from the Camera to the Player instead of from the Player to the Camera? The Camera isn't inside a BoxCollider and so it can get the detection on the BoxCollider the player is inside.
Eg.. instead of
if (CapsuleCast(fromPlayer, toCamera)) ...
do
if (CapsuleCast(fromCamera, toPlayer)) ...
Hey! Thanks for your idea, it does indeed work, I must admit I haven't thought about it, it's kind of embarrassing. x)
Thanks a lot!
Well, sometimes you have to stop thinking inside the box and think outside the box. ^^
