Bouncing balls miss collisions, bounce the wrong direction, of lose momentum on one axis when hitting a corner
It appears that your code is fighting with the physics engine about who gets to control the velocity vectors of the balls.
When there is a collision between two rigidbodies, then the Unity physics ...

Fast way to calculate angular intervals and occlusion of circular objects in a 2D vision cone
Here are some optimization suggestions:
1. Filter unnecessary tests
Objects located outside the field of view circle(distance>r1+r2) do not need to be detected. ...

Rotating 2D sprite around tilted Y axis
I think this would be easiest using SKTransformNode.setQuaternion instead.
This makes it easy to express a rotation by some angle around any axis you choose, rather than only rotations around the ...

Rotating 2D sprite around tilted Y axis
Try creating the art so that the red line is horizontal, then rotate it in Swift on its zRotation, and animate scaling along the ...

How to make redirected player movement respond to same key?
Not tested, but you could try looking at which keys the player is pressing when they're warping and setting the velocity x/y values to 0 when they're released depending on how much the movement is ...

Why won't my bullets shoot?
It should have been .up instead of forward, because forward is for 3D. Then *-1 because I want it to go in the opposite direction.

Simulated light for a 2D tile-map with just SDL2?
I think what you want is to create a black texture with the same size as your screen, set it as the render target, render blurry white circles to it at the locations of the light sources, with the ...

Optimal Approach for Transmitting and Rendering Large Pixel Art Game Maps in Unity
What I would suggest in this case is the following:
Rendering details like pixel colour, are usually not crucial to game logic. Since you will need to render the 1000x1000 map as a texture, it is ...

Sprite chasing a target using move_towards_ip does not move
pygame.sprite.Group.draw:
Draws the contained Sprites to the Surface argument. This uses the Sprite.image attribute for the source surface, and Sprite.rect for the position.
So we need to update ...

Fast way to calculate angular intervals and occlusion of circular objects in a 2D vision cone
My first move would be to use a Raycast at regular intervals between the start & end angles. In other words:
begin at the starting angle
perform a raycast ...
