Example 2 with Vec2

use of com.almasb.fxgl.core.math.Vec2 in project FXGL by AlmasB.

the class PhysicsControl method reposition.

/**
 * Repositions an entity that supports physics directly in the physics world.
 * Note: depending on how it is used, it may cause non-physical behavior.
 *
 * @param point point in game world coordinates (pixels)
 */
public void reposition(Point2D point) {
    double w = getEntity().getWidth();
    double h = getEntity().getHeight();
    Vec2 positionMeters = physicsWorld.toPoint(new Point2D(point.getX() + w / 2, point.getY() + h / 2));
    body.setTransform(positionMeters, body.getAngle());
}

Example 3 with Vec2

use of com.almasb.fxgl.core.math.Vec2 in project FXGL by AlmasB.

the class PhysicsWorld method createGroundSensor.

private void createGroundSensor(Entity e) {
    // 3 is a good ratio of entity width, since we don't want to occupy the full width
    // if we want to ban "ledge" jumps
    double sensorWidth = e.getWidth() / 3;
    double sensorHeight = 5;
    // center with respect to entity center
    Point2D sensorCenterLocal = new Point2D(0, e.getHeight() / 2 - sensorHeight / 2);

    polygonShape.setAsBox(toMetersF(sensorWidth / 2), toMetersF(sensorHeight / 2), new Vec2(toMetersF(sensorCenterLocal.getX()), -toMetersF(sensorCenterLocal.getY())), 0);

    e.getComponent(PhysicsComponent.class).body.createFixture(fd);
