Sniper teleportation

 Author: Pedro Polanco III

    When I was creating the sniper class for our game, I was trying to make him teleport between the corners of the map and he would instead be teleporting outside of the map. This would obviously cause issues if it's not fixed because the player would not be able to kill the enemy due to him being outside of the map making it so they cannot progress.

    When I was debugging the code, I realized that I was using improper points to teleport the enemy. When I was calculating the size of the floor, he would grab a point just outside of the room corners because I calculated the corners incorrectly. The way I fixed this is by using the bottom corners of the walls to determine what spots where valid and then I subtracted by a small amount to further push the position further into the map, that way the sniper should never be spawned outside. Fixing this allows for the player to properly interact with the enemy and clear the room

Adding assets to every enemy -- Owen Meyers

      As with every game, it is very important to have assets to denote which enemy is which. Being able to tell at a glance what enemy you are encountering before receiving a face full of buckshot is incredibly important. The issue for Project [REDACTED] is that we didn't have any artists working full time to deliver assets for the enemies. Thus, it fell upon me, the designer of the asset pipeline, to acquire assets for every enemy. This led to having to fix models and integrate animations, with each problem being subtly different.     Take, for example, the shotgunner model. His original model was designed for an OpenGL renderer, and was flipped 180 degrees for that very reason. In addition to this, he was also placed halfway in the ground, likely due to something required for that game's collision to function. Fixing this model to function for our renderer required that it be re-rigged and most of the animations acquired from Mixamo. With the help of Kris, and several hours

Sphere to AABB collision

       I had a problem today when trying to detect sphere to AABB collision. For some reason the collision check that I made was never turning true even though I could clearly see the sphere hitting the AABB. This was a big problem as we needed this collision to detect whether any entities are hitting walls.     I discovered that the problem with this bug was that I was improperly getting the closest point in the AABB to the sphere. The way I fixed this problem this problem was by getting the max vertex that the circle center could be and using that to get the closest point on the AABB to then determine the minimum vertex between the sphere's max vertex and the max of the AABB.  Once I found this point, I could properly compare the distance of that point to the center of the sphere. This solution will allow detection between walls and any sphere collider such as the player collider, and enemy collider. This is very important to make sure they both stay within the level bounds.
