Title: Camera Collision
Post by: Nog on June 02, 2014, 12:36:45 PM

Hello Playmaker Forum,

I have just finished the 3rd person camera tutorial from the Hutong Games video tutorials. It is a good 3rd person camera system; however, this camera setup does not prevent the camera from going through walls and other obstacles. How would I go about building a camera collision system into this setup using Playmaker so that the camera does not go through walls and other objects? Any ideas?

Thank you for your help.

Thanks,

Nog

make you camera have a parent. This parent would be your actual camera position.

When it collide, your camera can not goes in.
Make a state when your camera position is not matching its parents position, it try to reach that position ;) (using iTween)

I suggest you to prevent that state (reach position) to do anything when your character is not moving anymore (to avoid some shaking problem)

that is how i would handle that ;)
this is simple, you can do more complicated things.

Raycasting would be your next bet- but I'm not sure that's as easy to explain. You should cast a ray from your player's head to your camera point- and position the camera at the ray's length, or intersection.
