Stage 2: Struggle Colliding

I struggled EXTREMELY with getting the rockets to collide with the floor and walls. Oddly enough, they collided perfectly fine with the enemies! I was particularly confused because both the walls/floors and the enemies were types of body nodes, thus using the same piece of code to register a collision.

I looked up the issue online, to no avail, really, until I stumbled upon a thread about a completely different problem where someone advised to change the physics engine. I am, in fact, using a different physics engine – Jolt. So I figured, I'll go into the settings, and I'll change it, just to see what happens.

I briefly checked out Jolt's settings page... and then I saw something.

"Areas Detect Static Bodies." This setting was OFF by default. This could actually apply, I figured, because my rockets are Area3Ds and the walls/floors are StaticBody3D nodes. I turned it on, and... my issue was solved. Slightly frustrated, but more so amused and relieved, I continued work, happy that my code was fine and my solution worked.

I introduced an exported property that allows for setting the amount of collisions a projectile may experience before it despawns, thus allowing, for example, for the rocket to explode through a wall! I might use this in the future for the v3 rocket laucher.

Stage 3: Style

One day after that, I was motivated to create a more convincing explosion. I watched a YouTube tutorial, and ultimately got something that looks quite nice:
