One of the benefits of creating a 3D game is that we can have a vertical element to play, adding in areas for players to snipe or high ground that players would intuitively go to. To help players traverse in these areas, we can use stairways. However, instead of creating the brush from scratch, we can use another tool of Prototype, Shape Tool.
In the Prototype tab, click on the Shape button to bring up the Shape Tool dialog box.
In the Shape Tool dialog, select the Shape Selector dropdown and then select Stair. Change the Width value to
5and click on Build Stair.
Next, raise the other room to fit the stairs and extend the colliders to fit our newly added ground.
