Example 11 with Polygon

use of org.valkyrienskies.mod.common.collision.Polygon in project Valkyrien-Warfare-Revamped by ValkyrienWarfare.

the class PhysicsObject method getPhysicsTransformAABB.

public AxisAlignedBB getPhysicsTransformAABB() {
    AxisAlignedBB subspaceBB = getBlockPositions().makeAABB();
    if (subspaceBB == null) {
        // The aabbMaker didn't know what the aabb was, just don't update the aabb for now.
        return null;
    }
    // Expand subspaceBB by 1 to fit the block grid.
    subspaceBB = subspaceBB.expand(1, 1, 1);
    // Now transform the subspaceBB to world coordinates

    // Set the ship AABB to that of the polygon.
