Example 1 with OnScaleEvent

use of org.terasology.engine.logic.characters.events.OnScaleEvent in project Terasology by MovingBlocks.

the class CharacterScalingSystem method onScaleByRequest.

@ReceiveEvent(priority = EventPriority.PRIORITY_TRIVIAL)
public void onScaleByRequest(ScaleByRequest request, EntityRef entity, CharacterMovementComponent movementComponent) {
    OnScaleEvent scaleEvent = new OnScaleEvent(movementComponent.height, movementComponent.height * request.getFactor());
    entity.send(scaleEvent);
    request.consume();
}

Example 2 with OnScaleEvent

use of org.terasology.engine.logic.characters.events.OnScaleEvent in project Terasology by MovingBlocks.

the class CharacterScalingSystem method onScaleToRequest.

@ReceiveEvent(priority = EventPriority.PRIORITY_TRIVIAL)
public void onScaleToRequest(ScaleToRequest request, EntityRef entity, CharacterMovementComponent movementComponent) {
    OnScaleEvent scaleEvent = new OnScaleEvent(movementComponent.height, request.getTargetValue());
    entity.send(scaleEvent);
    request.consume();
}

Example 3 with OnScaleEvent

use of org.terasology.engine.logic.characters.events.OnScaleEvent in project Terasology by MovingBlocks.

the class CharacterSystem method onScaleCharacter.

@ReceiveEvent
public void onScaleCharacter(OnScaleEvent event, EntityRef entity, CharacterComponent character, CharacterMovementComponent movement) {
    // TODO: We should catch and consume this event somewhere in case there is no space for the character to grow
    Prefab parent = entity.getParentPrefab();
    // adjust movement parameters based on the default values defined by prefab
    CharacterMovementComponent defaultMovement = Optional.ofNullable(parent.getComponent(CharacterMovementComponent.class)).orElse(new CharacterMovementComponent());
    final float factor = event.getFactor();
    movement.height = factor * movement.height;
    movement.jumpSpeed = getJumpSpeed(factor, defaultMovement.jumpSpeed);
    movement.stepHeight = factor * movement.stepHeight;
    movement.distanceBetweenFootsteps = factor * movement.distanceBetweenFootsteps;
    movement.runFactor = getRunFactor(factor, defaultMovement.runFactor);
    entity.saveComponent(movement);
    // adjust character parameters
    CharacterComponent defaultCharacter = Optional.ofNullable(parent.getComponent(CharacterComponent.class)).orElse(new CharacterComponent());
    character.interactionRange = getInteractionRange(factor, defaultCharacter.interactionRange);
    entity.saveComponent(character);
    // refresh the entity collider - by retrieving the character collider after removing it we force recreation
    physicsEngine.removeCharacterCollider(entity);
    physicsEngine.getCharacterCollider(entity);
    // Scaling a character up will grow them into the ground. We would need to adjust the vertical position to be
    // safely above ground.
    Optional.ofNullable(entity.getComponent(LocationComponent.class)).map(k -> k.getWorldPosition(new Vector3f())).map(location -> location.add(0, (event.getNewValue() - event.getOldValue()) / 2f, 0)).ifPresent(location -> entity.send(new CharacterTeleportEvent(location)));
