Help making a raycast hit another object through a wall

Hello guys. I will be working on the script for my armor piercing sniper rifles that can hit targets behind cover. I have no idea how to simulate that using raycast. I cannot just ignore the wall collider as it needs it to create a wall hit effect and a big hole decal in the wall, just for realism's sake. The script instantiates particle systems when raycast hits a collider

 

I haven't tried this and I'm sure someone already has a cool script that can do this and might come to your rescue. But I wonder if you couldn't just cast a raycast from the wall to further on? Or could you use two raycast where one hits the wall and the other ignores it? Again, not tried, just a thought.

 

Use layers and add whatever objects you want to raycast and while raycasting use that layer.

This will simply ignore everything else.

Writing on phone, cant give an example or even verify that it works, but there should be enough examples for this

 

Good idea. I will see if it works.

 

RaycastAll is another route.
