Example 2 with RetainComponentsComponent

use of org.terasology.engine.logic.common.RetainComponentsComponent in project Terasology by MovingBlocks.

the class EntityAwareWorldProvider method setBlocks.

// SetBlocks, not SetBlock, is currently triggered by the engine whenever a player places a block.
// This allows for several useful features, such as quickly synchronizing placement across networks.
// However, this means that even if only one block is placed, this is the method being called.
// It must be overridden here to allow an OnChangedBlock event to be properly sent for placed blocks.
@Override
public Map<Vector3ic, Block> setBlocks(Map<? extends Vector3ic, Block> blocks) {
    if (GameThread.isCurrentThread()) {
        Map<Vector3ic, Block> oldBlocks = super.setBlocks(blocks);
        for (Vector3ic vec : oldBlocks.keySet()) {
            if (oldBlocks.get(vec) != null) {
                EntityRef blockEntity = getBlockEntityAt(vec);
                // check for components to be retained when updating the block entity
                final Set<Class<? extends Component>> retainComponents = Optional.ofNullable(blockEntity.getComponent(RetainComponentsComponent.class)).map(retainComponentsComponent -> retainComponentsComponent.components).orElse(Collections.emptySet());
                updateBlockEntity(blockEntity, vec, oldBlocks.get(vec), blocks.get(vec), false, retainComponents);
            }
        }
        return oldBlocks;
    }
    return null;
