Moving around a static object

Hi everyone,

I have an enemy (SAW) Saw is moving randomly on game area When saw hits the box with the green X position, I want to move the saw around the box. But how? Any suggestion?

Thanks

 

First of all some questions:

1. Do you know that the object will always be rectangular in shape?
2. Will all enemy saws have the same radius- or can they be different sizes?

For the moment, I am going to assume the answers are (1) yes and (2) same radius. So you could try something like this:

1. Create 4 empty GameObject children on the cube.
2. Place each at a corner of the cube offset (extending out in a straight line from the centre point) by the radius of the saw.
3. Place a trigger collider on each of the 4 cube faces. Logically, each collider points to the corner child (from point 2) that is anti-clockwise from that collider.
4. Now when a saw hits one of the colliders, set it on a move towards the linked child corner.

 

You made my mind clear thanks its done.

 

I would recommend doing pretty much this, but instead of colliders assign it the empty objects as waypoints and do all the corner checking in a script. I think that would be less prone to unexpected behavior, just a hunch. And likely easier to build more complex setups with multiple saws on different paths without them affecting each other.
