Item Display Menu

 Author: Jymeer Wilkins


Problem:

The problem I ran into with the item menu was a index problem with the for loop. I would store all the items that the player picks up into an array, but I didn't want to add each individual item in the display. For every duplicate item in the list, I would increment an integer. So, in the display, there would be the item, and a number showing how many the player had of that item. would loop through the list to get each item in the list, and for loop through the list again to check each item. If the item I was checking was identical to the item I was currently on in the first loop, then I would delete that item from the list so the same items wouldn't get checked twice. Then I would increment the number. The problem I was running into was a problem with the indexes. Since I was deleting items from the list, it would mess up the last index of the loop. It would make the loop end earlier than it needed too.

Solution: 

I struggled with this problem for a bit, because I didn't exactly know what was wrong. I picked up all the items, and stepped through the loops to see what the problem was. Once I realized why the loop was ending early and not going completely through, I kind of already knew how to fix it. I took the length of the array that was passed into the function and stored it in a variable. Then I would set that variable as the last index for the loop. This made it so the last index wasn't continuously changing. This fixed my problem.

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...
