Methods
void begin() #
Called before processing of entities begins.

void begin() {
_tickTime += world.delta;
//if (_tickTime < 10000) print("_tickTime ${_tickTime}");
}
bool checkProcessing() #
inherited from EntityProcessingSystem
Returns true if the system should be processed, false if not.
docs inherited from EntitySystem
bool checkProcessing() => true;
void deleted(Entity e) #
inherited from EntitySystem
void deleted(Entity e) {
if (_contains(e)) {
_removeFromSystem(e);
}
}
void disabled(Entity e) #
inherited from EntitySystem
void disabled(Entity e) {
if (_contains(e)) {
_removeFromSystem(e);
}
}
void end() #
inherited from EntitySystem
Called after the processing of entities ends.
void end() {}
void initialize() #
Override to implement code that gets executed when systems are initialized.
docs inherited from EntitySystem
void initialize(){
_animatableMapper = new ComponentMapper<Animatable>(Animatable, world);
}
void inserted(Entity entity) #
inherited from EntitySystem
Called if the system has received an entity it is interested in, e.g. created or a component was added to it.
void inserted(Entity entity) {}
void process() #
inherited from EntitySystem
This is the only method that is supposed to be called from outside the library,
void process() {
if(checkProcessing()) {
begin();
processEntities(_actives.readOnly);
end();
}
}
void processEntities(ReadOnlyBag<Entity> entities) #
inherited from EntityProcessingSystem
Any implementing entity system must implement this method and the logic to process the given entities of the system.
docs inherited from EntitySystem
void processEntities(ReadOnlyBag<Entity> entities) => entities.forEach((entity) => processEntity(entity));
void processEntity(Entity entity) #
Process a entity this system is interested in.
docs inherited from EntityProcessingSystem
void processEntity(Entity entity) {
var animatable = _animatableMapper.get(entity);
animatable.l.iterateAndUpdate((anim) {
if (anim._t0 < 0) {
anim._t0 = _tickTime;
anim.onBegin(entity, _tickTime, anim._t0);
}
var cont = (anim._t0 <= _tickTime)? anim.onTick(entity, _tickTime, anim._t0) : true;
if (!cont) {
anim.onEnd(entity, _tickTime, anim._t0);
}
return cont ? anim : anim.next;
});
}
void removed(Entity entity) #
inherited from EntitySystem
Called if an entity was removed from this system, e.g. deleted or had one of it's components removed.
void removed(Entity entity) {}
