Example 2 with NoiseModule

use of net.tropicraft.core.common.dimension.noise.NoiseModule in project Tropicraft by Tropicraft.

the class VolcanoGenerator method getVolcanoHeight.

/**
 * Get the height of volcano generation at the given x/z coordinates, without needing
 * to generate any blocks.
 *
 * @param groundHeight The current known heightmap level at the given coordinates.
 * @param x Block x position
 * @param z Block z position
 * @return The height value of the volcano generating near the given coordinates, at the
 * specified x and z. If there is no nearby volcano, returns -1.
 * @apiNote This only does a somewhat rough calculation -- it ignores the caldera "edge"
 * and treats volcanoes as completely flat at the top (ignoring random holes).
 * <p>
 * The latter is actually beneficial to the main use, village gen, because otherwise
 * village pieces may generate directly on top of a hole (and thus inside the volcano).
 * <p>
 * It also duplicates a significant amount of logic from {@link #generate(int, int, IChunk, SharedSeedRandom)},
 * but I have yet to find a nice way to deduplicate that logic. This whole class could use
 * a rewrite at some point with these goals in mind.
 * <p>
