Develop a Sprite and Platform Game - Unity 3 Game Development - page 32

One last thing for the Gizmos : if we want to see our gizmos in the game scene, we can click
on the Gizmos tab on the top-right corner of the game scene:
Creating a key and door
In this step, we will create the finish point, which is the door in this case. We will also create
a Trigger Collider , which makes it so that the player can't end the game if he/she didn't
collect our item; of course it's the key to our door.
Prepare for Lift Off
Let's prepare and make sure that we have all the graphics that we need; go to the
Graphics folder in the Project window, and make sure in our subfolder Level , we have
doorClose.png , doorOpen.png , and key.png . Let's get start.
Engage Thrusters
Here, we will create the object's Key and Door . Let's do this as follows:
1. Let's create the new material for our key, so go to Assets | Create | Material , name
it M_Key , and set the following:
Shader : Transparent | Cutout | Specular
Main Color : R: 255 , G: 166 , B: 0 , A: 255
Specular Color : R: 236 , G: 224 , B: 26 , A: 0
Shininess : Drag the dragger almost to the right side
Base (RGB) TransGloss (A)
Drag-and-drop our key.png in the Graphics/Level to the texture
thumbnail in the material inspector:
