Hallways and Room Overlap

Author: Najee Jackson

Problem

This week, I worked on fixing room overlap. To do this, I made a MakeHall Function, which would build halls between rooms, but when building levels, room walls would overlap with doors connected to other rooms, blocking the player from progressing through the level. I also ran into the issue that a doorway would not spawn at the end when making halls. Which broke emersion as the player went through the level.

Solution

To fix the first problem, I had to check for overlapping actors in my randomized-level script after I spawned a room. To do this, I made a function that would take each room's door array and loop through it to see if any actors were overlapping the door actor. If so, I got the class name and checked whether it was a wall collision or another door. If it was one of those actors, I removed it from that room's array and destroyed the actor. This worked most of the time, but sometimes, it would not register that something was overlapping with a door, and a wall would spawn on top, or it would destroy the walls next to the door and leave a giant gap. To fix this issue, I made another hitbox called DoorOverlapBox on the door that would only collide with objects that spawned on top of the door actor. Instead of checking the door actor for overlapping actors, I checked that door's DoorOverlapBox. That gave me a more accurate overlapping and eliminated the deletion of side walls and fixed walls spawning on top. To fix the second issue, I added a function that spawned a door at the end of the room if its hall bool was true. The hardest part was figuring out how to get the doors position right no mater the rotation. To do this, I used the room's right vector and multiplied it by 400 so it would move the door from the outside of the hall to the middle. I also used the actor's location and rotation and the room's tile length to figure out the door's position and which way the door should face.

Procedural Generation - Room NavMesh Spawning

Image
 Author: Najee Jackson Problem When generating rooms, enemies didn't spawn, so the player just walked around in an empty level. To fix this, I wanted to create a spawner in each room of a certain size, but the spawner only worked in areas with valid nav meshes. My level had none in it since it was procedurally generated, which resulted in the spawner not spawning enemies, and if it did, enemies would not move since they couldn't find a valid NavMesh. Solution To fix this, I wanted to spawn a Navmesh Bounds Volume whenever a room was created, but I soon learned that you couldn't spawn NavMesh Bounds in Unreal Engine 5. After learning this, I searched for ways to spawn a nav mesh in a procedurally generated map. I wanted to avoid creating a giant Nav Mesh encompassing the entire map. Since I feared that the spawner would spawn enemies far away from the player, it also would be a waste of processing power to have an active nav mesh in areas that enemies never use. One way that...

Powerups and Wall clipping

Image
  Author: Colyn Reed Problem          For this week, I continued working on having a working map for the player to navigate and explore. On this map, I added powerups for the player to pick up. The power ups I added was the Health boost powerup which gives the player more max health and a speed boost powerup which gives the player more max speed. Along with the powerups, I added wall clipping so that the player doesn't get lost behind any walls. Solution     Getting the players max health to change was the first issue I ran into. I had to create a whole new event inside the health component that changes the max health of the player instead of changing the current health of the player. The speed boost powerup was easier to manage except that its hard to notice at first when you pick it up, but once you get it stacked its noticeable. For the wall clipping, I had to create a whole new material for the walls and the hardest part with that was get...
