Example 31 with Matrix4

use of com.badlogic.gdx.math.Matrix4 in project nhglib by VoidZombie.

the class LightingSystem method process.

@Override
protected void process(int entityId) {
    NodeComponent node = nodeMapper.get(entityId);
    LightComponent light = lightMapper.get(entityId);
    light.light.position.set(node.getTranslation());
    light.light.setTransform(node.getTransform());
    switch(light.type) {
        case SPOT_LIGHT:
        case DIRECTIONAL_LIGHT:
            Matrix4 tempMatrix = MatrixPool.getMatrix4();
            tempMatrix.set(node.getTransform());
            tempMatrix.translate(0f, 1f, 0f);
            Vector3 direction = VectorPool.getVector3();
            Vector3 tempVec = VectorPool.getVector3();
            direction.set(light.light.position).sub(tempMatrix.getTranslation(tempVec));
            light.light.direction.set(direction);
            MatrixPool.freeMatrix4(tempMatrix);
            VectorPool.freeVector3(direction, tempVec);
            break;
