Example 90 with Redirect

use of org.spongepowered.asm.mixin.injection.Redirect in project SpongeCommon by SpongePowered.

the class MixinNetHandlerPlayServer method processVehicleMoveEvent.

/**
 * @author gabizou - June 22nd, 2016
 * @author blood - May 6th, 2017
 * @reason Redirects the {@link Entity#getLowestRidingEntity()} call to throw our
 * {@link MoveEntityEvent}. The peculiarity of this redirect is that the entity
 * returned is perfectly valid to be {@link this#player} since, if the player
 * is NOT riding anything, the lowest riding entity is themselves. This way, if
 * the event is cancelled, the player can be returned instead of the actual riding
 * entity.

 * @param playerMP The player
 * @param packetIn The packet movement
 * @return The lowest riding entity
