[Help]How to disable and enable the Entity?

When the character eats gold coins, the coins disappear.
DONT DESTORY ENTITY! JUST LOOK LIKES SETACTIVE TRUE OR FALSE.

 

Code (CSharp):

1.         static setEntityEnabled(world: ut.World, entity: ut.Entity, enabled: boolean) {
2.             let hasDisabledComponent = world.hasComponent(entity, ut.Disabled);
3.             if (enabled && hasDisabledComponent) {
4.                 world.removeComponent(entity, ut.Disabled);
5.             }
6.             else if (!enabled && !hasDisabledComponent) {
7.                 world.addComponent(entity, ut.Disabled);
8.             }
9.         }

This is working!

 

hello, why i can not iterate through parent entity when children have ut.Disabled component? with such code:

Code (JavaScript):

1. let childCount = ut.Core2D.TransformService.countChildren(world, entity);
2. for (; childCount > 0; childCount--) {
3. let child  = ut.Core2D.TransformService.getChild(world, entity, childCount-1);
4. }

, i can disable children but can not enable them after, is it bug or normal, and pls make possible to use dynamic array of dynamic array of EntityReference, serialization failed in that case, or just make it impossible to create in editor...

 

Hello,
How do you get the entity from the system ?

 

Yes, U need remove

ut.Disabled

first!

 

Like this:

Code (CSharp):

1.  OnUpdate(): void {
2.             let tmp_GameState = this.world.getConfigData(game.GameConfig);
3.             if (tmp_GameState.State != game.GameState.Play) return;
4.             this.world.forEach([ut.Core2D.TransformLocalPosition, game.Scroller], (transformPosition, scroller) => {
5.                 let posistion = transformPosition.position;
6.                 posistion.y -= scroller.speed;
7.                 transformPosition.position = posistion;
8.             });
9.         }

 

I think once you disabled an entity your world.forEach won't find them any more. You should instead use an EntityQuery and explicitly querying for the 'Disabled' component.

 

Entities with a ut.Disabled component will indeed not show up in a world.forEach if you have not included ut.Disabled in the filter.

If you include it, you will loop over all disabled entities with the other matching components:

Code (CSharp):

1. this.world.forEach([ut.Entity, game.ExampleComponent, ut.Disabled], (entity, exampleComp) => {
2.        //Code to be executed on every disabled entity which has game.ExampleComponent.
3. });
