#stealth game

When the goblin is in a vision cone, a ray is cast to it and if there is nothing blocking the guard's vision, the guard checks the light visibility of the goblin.

The guard starts with a base vision threshold, we'll say 50 for this example. This vision threshold is multiplied by the VisionArea's vision modifier variable, in this case 1.3 which makes the new vision threshold 65. This modified threshold is then multiplied again by the alert state of the guard. Since the guard in this example is vibing, he's in a low alert state which will set this modifier to 1.3 again. We multiply the modified threshold by that to get 84.5. We then take this twice-modified threshold and compared it to Little Goblin's light visibility at the time of being seen. (This number is explained in a previous post but it's basically just a number from 0-100 representing the goblin's illumination in the scene). If Little Goblin's light visibility is lower than the guard's modified vision threshold, the guard cannot see the goblin.

This should make building out the lighting in the levels and getting to stealth through them super fun! Even more fun is that I set it up to be modular, so I can create as many custom cones as I want, made with as many vision areas as I want, and I can change the modifier values on all of them. This'll let me make different cones for the guards' different alert levels, different activities, and whatever else I want! I also made it so that these vision cone nodes can be added to whatever else I want to give vision, from animals to cameras to sentient brooms.
