Slow Projectile

Author: Josiah Jones

Problem: 
    
    So this week I was making a slow projectile for my enemy to shoot three shots of basic bullets. This slow projectile was supposed to slow the player on hit and last just for a couple of seconds before the player returns back to there original movement speed. But instead what was happening was either the slow effect would stack, speed would end up at 0(when more than one slow projectile hit at the same time), nothing would happen, or the original speed will get lost and become the slow speed.

Solution:
    
    To address the issue, I initially implemented the slow effect in the player blueprint instead of the slow projectile blueprint. I created a delegate in the player blueprint that binds to the slow effect event. In the slow projectile blueprint, I call this delegate when the projectile hits the player, ensuring consistent tracking.
    However, this solution had a limitation when we introduced a power-up that permanently increased the player's movement speed. The original speed retrieval didn't account for this boost, resulting in an incorrect return value after being slowed. to resolve this, I updated the original speed every time a power-up was acquired. i achieved this by capturing the new base speed in the movement speed boost event graph.

Slow Projectile Event Graph:

Notes: Shows old webbed event when everything was done in its event graph. Shows delegate call.

Player Event Graph:


Notes: Shows new web event. Shows delegate binding to event. Shows grabbing the original Speed.

Movement Speed Boost Event Graph:


Notes: Shows updating original speed after increased form powerup.

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...
