Examples with TreeFacet org.terasology.core.world.generator.facets.TreeFacet used on opensource projects

Example 1 with TreeFacet

use of org.terasology.core.world.generator.facets.TreeFacet in project Terasology by MovingBlocks.

the class DefaultTreeProvider method process.

@Override
public void process(GeneratingRegion region) {
    SurfaceHeightFacet surface = region.getRegionFacet(SurfaceHeightFacet.class);
    BiomeFacet biome = region.getRegionFacet(BiomeFacet.class);
    List<Predicate<Vector3i>> filters = getFilters(region);
    // these value are derived from the maximum tree extents as
    // computed by the TreeTests class. Birch is the highest with 32
    // and Pine has 13 radius.
    // These values must be identical in the class annotations.
    int maxRad = 13;
    int maxHeight = 32;
    Border3D borderForTreeFacet = region.getBorderForFacet(TreeFacet.class);
    TreeFacet facet = new TreeFacet(region.getRegion(), borderForTreeFacet.extendBy(0, maxHeight, maxRad));
    populateFacet(facet, surface, biome, filters);
    region.setRegionFacet(TreeFacet.class, facet);
