# Which sensor is used for collision detection?

## Which sensor is used for collision detection?

A collision sensor is a piece of electronic safety equipment that detects an impact through vibrations. Collision sensors are also known as impact sensors.

### Which method is used to collision detection between to rectangle objects?

Axis-Aligned Bounding Box One of the simpler forms of collision detection is between two rectangles that are axis aligned — meaning no rotation. The algorithm works by ensuring there is no gap between any of the 4 sides of the rectangles. Any gap means a collision does not exist.

#### How does game collision detection work?

Continuous collision detection techniques attempt to find when two bodies collided between the previous and the current step of the simulation. They compute the time of impact, so we can then go back in time and process the collision at that point.

How do you find the collision between Rectangle and Circle in Pygame?

1. Check that their bounding boxes intersect.
2. Check whether any vertex of the square is inside the.
3. Check if the center of the circle is inside the rectangle.
4. Check for circle – edge intersections.

What is axis aligned box in collision detection?

Axis-Aligned Bounding Box. One of the simpler forms of collision detection is between two rectangles that are axis aligned — meaning no rotation. The algorithm works by ensuring there is no gap between any of the 4 sides of the rectangles.

### How do collision algorithms detect collision in 2D games?

Algorithms to detect collision in 2D games depend on the type of shapes that can collide (e.g. Rectangle to Rectangle, Rectangle to Circle, Circle to Circle).

#### How to detect collisions with a bounding sphere?

Using bounding spheres to detect collisions is a bit more complex than AABB, but still fairly quick to test. The main advantage of spheres is that they are invariant to rotation, so if the wrapped entity rotates, the bounding sphere would still be the same.
