Movement System

Source: client/engine/systems/SystemsFunctions/MovementSystem.cpp

Purpose: Apply velocity and acceleration to entity Transforms.

Components used:

  • Transform (x, y, rotation, scale)
  • Velocity (vx, vy, accelerationX, accelerationY)

Behavior​

  • Update position: transform.x += velocity.vx * dt and transform.y += velocity.vy * dt.
  • Update velocity by applying acceleration: vx += accelerationX * dt.

Main signature​

void MovementSystem(Eng::registry &reg, const float dt,
    Eng::sparse_array<Com::Transform> &transforms,
    Eng::sparse_array<Com::Velocity> &velocities);

Notes​

  • dt typically comes from game_world.last_delta_.
  • No collision or bounds handling here; this is simple kinematic motion.
