Interactable and Door collision

 Author: Cameron Taylor

I wanted to get interactables working so I made a child off of Entity and gave them special attributes that I could use to figure out what each interactable did. I then used health from entity as how much health is used to heal the player. A problem I ran into was update was called too fast! This is weird because usually the code works, but since update is called about 900 times a second then interacting with interactables started breaking. A prime example was with the starting doors. When pressing 'E' to start there was a chance that it would start twice and fill buffers twice and this took a painful amount of time to track down.

To solve this I had to put breakpoints everywhere and see why the function was being called twice. Took more time than I would like to admit, but the final solution was putting a boolean check inside start to make sure the start code only happens once. Before this it was starting 2 sometimes 3 times.

Adding assets to every enemy -- Owen Meyers

Image
      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.
