Obstacle Course
We will create an obstacle course similar to the one in the screenshot above with the parts functioning as follows:

Add the above code to your Update method and test your player movement in game.

Multiply your x and y values by Time.deltaTime to ensure our player movement is frame rate independent

Add another variable called moveSpeed and multiply your x and y values by it.

Our plan now is to:
Our plan now is to:
- Hide the floating obstacles until they are ready to drop by disabling the MeshRenderer.
- Disable gravity on the Rigidbody until the objects are ready to drop then enable it.
We need a reference to the MeshRenderer and the Rididbody

It's good to also have a variable to adjust the amount of time before the obstacles fall.

Now that we have a reference to these components we can manipulate their properties:

In the Update method we can now make the object visible after 3 seconds and enable the gravity.

Now we need to adjust our program:
Now we need to adjust our program:
- to ensure that the score doesn't increase when the player bumps the same object more than once.
- to ensure that the objects only turn red when they collide with the player.
Add the built-in Player tag to your Player Game Object.

This will allow us to identify when the Player has collided with something.

Now try adding an IF-Statement to your ObjectHit Script to only turn red when colliding with something tagged as "Player".

We should also tag everything we have hit so that we only increase the score when we collide with something new:
