A simple physics simulation with ECS architecture (entity component system).
kotlin simulation 2d physics ecs entity component system
An entity is basically a composition of components.
- Shape (Interface) with a color
- Circle (with a radius)
- Collider of "merge" or "elastic" type and with a weight - used by collision system. If two objects has the same collider type they are either merged or bounce during a a collision
- Destructor - if other objects collide with this one they will disappear
- GravitySource with a strength - pulls other objects (if they have Velocity) towards this one
- Velocity - used by position system to change... the positon of the object
- Position - position of the object
A system changes the state of an entity. Implemented systems:
- CollisionSystem (merges or makes objects bounce from each other after the collision)
- DestructionSystem (remove objects)
- GravitationalSystem (pull objects together)
- PositionSystem (calculates position for moving objects)
