Question 1

the vines in animal well display pixel perfect deformation when the pc moves through them. they also display rope physics but do not appear to be implemented by jointed segments of physics rigidbodies ...

Question 2

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 3

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 4

How do I deal with collisions that have small relative velocities, but external forces such as gravity? Imagine a scenario with a box in 2D, rotated 30 degrees, and placed on the ground. Gravity acts ...

Question 5

In my collision protocol when a hit is found I’m using AABB faces to determine a reflected direction where the mobile must move (see picture left). This is easy as we just need to invert the sign of ...

Question 6

I'm trying to implement a PGS solver for collision response, but I'm currently stuck. How the problem manifests is, for the example of a box resting on the ground, if the box is given a small rotation ...

Question 7

CONTEXT: I am implementing a basic 3D character controller from scratch in Unity. For collisions, I do a capsule cast in the direction of the player velocity and use the collide and slide algorithm to ...

Question 8

I have a 2D circle, defined from: c = circle(position = (x,y), radius = r) I also have a 2D rectangle defined from ...

Question 9

I've just started getting into 2D game development and have been experimenting with some 2D collision and correction logic in canvas. I'm trying to debug this block of code and understand why it is ...

Question 10

I've written two main functions who's purpose is to detect and resolve collisions between a moving rectangle and a non-moving rectangle. I have a decent understanding of how the algorithm works, and ...

Question 11

I'm trying to create a particle simulation (solar system kind). Until now my particles have no spin so the collision is rather simple ...

Question 12

I'm making a game prototype in Godot. My player character is a ship that moves around in 3D space without gravity. I have some simple code that adds a knock back force to the player on collisions ...

Question 13

I'm coding a 2d physics engine in python, and I'm struggling to understand the right way to implement collision resolution when there are multiple contact points. Consider a very simple collision case ...

Question 14

What methods should be used to create such a sphere in UNITY? This collider seems to deform in real-time, squeezing and monitoring collision information when the sphere collides. I cannot achieve this ...

Question 15

I am currently creating an environment to train aim-bot AI's for my game. It is a 2d world made of complex polygons, and the goal is to have the AI's shoot ricocheting bullets. Using a ray-casting ...
