COLOR CHANGE VIA MOUSE CLICK WITH MULTIPLE OBJECTS

PreviousPLAYER SCRIPTNextPLAYER SCRIPT

Last updated 1 year ago

OBJECTIVE: Create a program that allows users to ONLY change the color of cubes, despite having other gameobjects within the scene.

ASSETS NEEDED

  • x3 Cube GameObject

  • x3 Sphere GameObject

SCRIPTS NEEDED

  • Player Script --> Attached to Main Camera

UNITY EDITOR

After all game assets have been added, attach tags to the gameobjects.

  • Cubes should have the tag "cube"

  • Spheres should have the tag "sphere"

BENEFITS OF TAGS

The biggest benefit of having gameobjects contain a tag is when you have a script find objects based on tags, even if the gameobject name changes, the program will not break. This makes code reusable and clean.

TAG CREATION

TAG ASSIGNMENT

SCRIPTS NEEDED

  • Player Script --> Attached to Main Camera

PLAYER SCRIPT

PURPOSE OF SCRIPT --> Recognize when the user clicks the left mouse button and fire a raycast from the mouse position. Script should be able to access the object that we hit and modify it's color if that object is a cube.
