physimple

Physimple aims to be the simplest(and capable) physics engine(currently for bevy)

WARNING

Beware for breaking changes with each update for now, as I am trying to make stuff work better by adding/removing stuff

Why?

Because I love physics and I love programming, so what is better? physics programming! besides, simulation physics can be restricting when you want to do some weird physics behaviour for games, and eventually i want people to be able to use this crate as a simple collisions solver.

What is currently working?

Simple AABB collisions(without rotations)
I got raycasts(tho they still need some more features, but first I will focus on more collision shapes)
That is pretty much it

Quickstart

TODO, for now you can check the examples just run cargo run --bevy/dynamic --example (showcase/simple/stress_2d) --release to see it in action

Do note that each physics component needs a GlobalTransform with it now.

bevy - physimple versions

bevy	physimple
0.5	0.1.0 - current

Comments

Replace hex-notation with binary in `CollisionLayer` docs

The CollisionLayer documentation has examples that uses binary operators, but the example integers are written in hexadecimal notation. This PR replaces each instance of hexadecimal notation (0x0000_0001) with binary notation (0b0000_0001).

The PR also fixes minor typos on the same page.

Square sensor only detects overlap at edges of another square
I ran into this issue trying to create a square hitbox that could detect which mobs falls within it. Below are images that illustrate the issue and a repository to reproduce.

The issue

A square sensor only registers overlapping bodies of square collision shape at the edges.

Expected result

The sensor registers the overlapping bodies throughout the area of the sensor.

Illustration

A controllable blue square has a light-gray sensor attached to detect the red square: The sensor detects the red square and turns yellow when the near edges are close: However, as the blue square moves further, the sensor no longer detects the red square:

Code to reproduce

Clone and run this repo:

git clone [email protected]:Havegum/bevy_physimple_sensor_issue.git cd bevy_physimple_sensor_issue cargo run

Use keyboard arrows or WASD to move the blue square.

Observe that the sensor changes color only when its edges touches the red square.
