Overview of the built-in systems in the game simulation.
Handles idle actions for game entities.
idle(..) updates the animation of the game entity. This requires the game
entity to have the Idle component. The function returns a time of 0 since
no actionsconsuming simulation time are taken.
Handles movement actions for game entities.
move_default(..) moves a game entity to the new position specified in the function
call. This requires the game entity to have the Move and Turn components.
Waypoints for the exact path are fetched from the pathfinder.
For every straight path between waypoints, the game entity is turned first, then
moved (same as in Age of Empires). If an animation is available for the Move
component, this animation is forwarded as the game entity's active animation to the
renderer. The function returns the cumulative time of all turn and movement actions
initiated by this function.
move_command(..) processes the payload from a move command to call move_default(..)
with the payload parameters.
