Communication Between Scripts In Unity Using GetComponent

Script communication is arguably one of the most important and most struggled with aspects of programming for new developers. But by learning and understanding how this works, you will be opening yourself up to a world of possibilities in the world of code.

How does it work?

There are a few different ways to go about this, and which one is best can vary depending on the scenario. But first and foremost, you are going to have to “Cache” either the script itself or the object it’s attached to.

Ok, but how do I use it?

If you are using one script to try and access another script that's attached to the same object.

Otherwise, if you’re trying to access scripts that are attached to different objects in the scene.

You can create a direct link to the other gameobject in the hierarchy.

Or you can search the hierarchy for an object by its name.


Or you can search the hierarchy for an object by its “Tag”.
