Example 1 with ClosestRayResultCallback

use of com.badlogic.gdx.physics.bullet.collision.ClosestRayResultCallback in project libgdx by libgdx.

the class RayCastTest method create.

    instructions = "Tap a box to ray cast\nLong press to toggle debug mode\nSwipe for next test\nCtrl+drag to rotate\nScroll to zoom";
    // Create the entities
    world.add("ground", -7f, 0f, -7f).setColor(0.25f + 0.5f * (float) Math.random(), 0.25f + 0.5f * (float) Math.random(), 0.25f + 0.5f * (float) Math.random(), 1f);

Example 2 with ClosestRayResultCallback

use of com.badlogic.gdx.physics.bullet.collision.ClosestRayResultCallback in project libgdx by libgdx.
