Question 1

I have a skeletal mesh with a Physics Asset assigned to it as such: This skeletal mesh is used within an ACharacter with collision settings as such: And an actor which has the overlap event as such: ...

Question 2

I'm new to Godot and following a tutorial, which spawns enemies randomly. However, I'm trying to improve on this by checking that the enemies don't spawn on top of the player and cause an instant loss....

Question 3

I'm creating a space sandbox game (godot 4.5), and the core of my building system is attaching parts together to create assemblies. Each assembly is one rigidbody3D that contains all the parts. Since ...

Question 4

I'm trying to make an enemy collide with collision tiles in GML. I don't think there should be anything wrong with it; it compiles, but every time the enemy either immediately disappears, or just ...

Question 5

Let's say I have like 500 Asteroids and I'm using SAT to determine whether a collision with the Spaceship object has happened. This would require an insane amount of CPU cycles, so it makes sense to ...

Question 6

Suppose you have two overlapping spheres \$A\$ and \$B\$, with centers \$c_{A}\$ and \$c_{B}\$ and radii \$r_{A}\$ and \$r_{B}\$. Let \$n = \operatorname{normalize}(c_{B} - c_{A})\$ be the collision ...

Question 7

I use Unity and the player controller in the game is acting strangely. It has a Character Controller but no Rigidbody. I use CharacterController.Move to make him ...

Question 8

I've recently been attempting (and failing) to create my own character controller for my 3D Unity game for around a week. I hate the Unity rigidbody physics system for making a character controller, ...

Question 9

I have been working on (somewhat) faithfully reimplementing pacman as a sideproject and means of better learning the rust framework Bevy. However, there is one part that I really cannot quite get my ...

Question 10

I'm currently working on my first game in Unity, and I'm having some trouble with attacking. Currently, I have a game object with a 2D capsule collider child. When the attack button is pressed, the ...

Question 11

So, in my breakout clone, I've encountered issues where the ball will sometimes phase through bricks and the borders if it collides with one and then immediately collides with another after. My guess ...

Question 12

I'm reworking physics in a 2d action platformer I'm developing (no engine, c++ / sdl). Here's the general movement logic for all characters: I calculate the offset I need to apply to the character I ...

Question 13

I'm working on a 3D physics engine, and I'm trying to implement OBB/OBB collision detection. I was able to find Bullet's implementation here, that I'm trying to adapt. However, I still want to know ...

Question 14

I wrote a BSP tree generation that takes a level mesh (basically a few thousand triangles), and creates a BSP tree. The generation seems to work, but when I traverse the tree, some splitting planes ...

Question 15

I'm developing a 2D game where multiple types of objects interact with each other through collisions. Currently, I'm using pygame.spritecollide() to detect ...
