This project has 2 scenes to indicate 2 different scenarios.

Steps to reproduce 1st scenario:
1. Open the attached project
2. Open and play 'TestSceneMovePosition' scene
3. Click left mouse button, to activate Rigidbody.MovePosition behaviour
4. Notice the OnTriggerEnter2D gets called even though the 'Projectile' GO was stopped in the middle of the way. (The white rectangle is set to stop rendering for a second if OnTriggerEnter is registered)

Note: Looks like using Rigidbody.MovePosition, the trigger enter will be registered no matter how far the projectile will actually stop.

Steps to reproduce 2nd scenario:
1. Open the attached project
2. Open and play 'TestSceneVelocity' scene
3. Click left mouse button, to activate Rigidbody.velocity behaviour
4. Notice the OnTriggerEnter2D gets called even though the 'Projectile' GO was stopped before it reached the target collider.

Note: If using Rigidbody.velocity and the obstacle is far enough, the collision is not registered.
