Example 1 with RayTraceContext

use of net.minecraft.util.math.RayTraceContext in project Bookshelf by Darkhax-Minecraft.

the class EntityUtils method rayTrace.

/**
 * Performs a ray trace for the look vector of an entity.
 *
 * @param entity The entity to perform a ray trace on.
 * @param length The distance to cast the rays.
 * @param blockMode The mode used when detecting blocks.
 * @param fluidMode The mode used when detecting fluids.
 * @return An object containing the results of the ray trace.
