We plan to use “Raycast” but don’t want to show on all the objects like the legos or the table.   [We know we are going to do something, but they arent specific.  Start by creating a quad called floor…]  This is the collider.

Create a quad – put it at origin, turn 90 on x.  Scale to 100×100

Name it “Floor”

Remove mesh-render component from floor.  You will see the collider (floor) outline.

Go to the properties window and at the top – change the layer to “Floor”

 

That is it for now.

 

Music

Create a blank game object and name it to background-audio

Add the component (audio source)

Use circle-select to pick the audio clip.

Unckeck – play on awake,

Check loop

Adjust volume to 0.1
