kandi X-RAY | Elastic-Collision Summary

Elastic-Collision is a Python library typically used in Simulation, Three.js applications. Elastic-Collision has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies after the encounter is equal to their total kinetic energy before the encounter. Perfectly elastic collisions occur only if there is no net conversion of kinetic energy into other forms (such as heat or noise) and therefore they do not normally occur in reality. During the collision of small objects, kinetic energy is first converted to potential energy associated with a repulsive force between the particles (when the particles move against this force, i.e. the angle between the force and the relative velocity is obtuse), then this potential energy is converted back to kinetic energy (when the particles move with this force, i.e. the angle between the force and the relative velocity is acute). The collisions of atoms are elastic collisions (Rutherford backscattering is one example).

Particles evading cursor and other particles

QUESTION

Particles evading cursor and other particles

Asked 2020-May-02 at 13:21

I'm trying to create a simple vanilla JS program where x amount of particles/objects are generated on screen and they need to evade each other and the mouse. For the overall evading I used https://gist.github.com/christopher4lis/f9ccb589ee8ecf751481f05a8e59b1dc and it worked just fine for the particles to avoid each other, but now I'm stuck on implementing the mouse evade functionality.

Everything I've tried has ended up with either particles overlapping with each other or some other bugs.

Does anyone have any tips on how to deal with this situation, or perhapse even a code snippet from previous project?

First I would change:
dist = distance(this._x, this._y, people[i].x, people[i].y) - 4 * this.radius;

to the following:
dist = distance(this._x, this._y, people[i].x, people[i].y) - (this.radius + people[i].radius);

That should give you realistic collisions when your circles are different radius

Then on the mouse object collision, I would start with something like:
