Question by casualbanana · Feb 28, 2014 at 06:07 PM · airaycasting

Raycast to detect how high blocks are infront of object

Hello, I am working on a simple game with a simple AI. Right now I am having troubles with ray casting. I want the AI to be able to detect how high blocks are in front of him. For example if there are 2 blocks in front of him, I want him to be able to jump to only clear those two blocks. I just need help with ray casting so it is able to detect how high the blocks are in front of him (is there 2, 3, etc).

I can provide more info if needed. Thanks!

Without your code, I can just give you theory. One way is to do the Raycast() from the maximum height he can jump. So the the position of the Raycast() would be something like:

 var raycastPos = transform.position + Vector3.up * maxHeight;

Raycast from the AI position in front to see if there is a block you need to jump over, if there is then ray cast from the max block height.

your raycasting will look like this
