How to OPEN A DOOR With KEY in UNITY - Easy Tutorial

In this video, you will learn how to make a door openable by collecting a key object, which can be something other, like a cylinder or a cube. The door will be animated every time the player approaches it. The door will only work if the player collects the key.

To open a door in Unity, you need to collect a key. You need to create a simple cylinder object (or any other) and possibly assign a material with the color (as you like). Then you have to resize it to the size that is slightly smaller than the player. Unlike the previous tutorial, this time you need to only add a script to the key object, which is pretty straightforward.

Add a simple script that will open the door once the key is collected. Don't destroy the key before opening the door! Put that line of code at the last part of the brackets.

I bought a computer from amazon for $95 it said it had a rtx 4090, and a core I 7, but on my computer it says core I 1 which i think is even better because of the lover number. also my computer had a GT730 4GB DDR3 Graphics Card HD+VGA+DVI Game graphics card. But once again i think its better because it has more numbers and letters. It was a really good deal, and i know what you may be thinking, but it runs really good actually. It cant run any games, but it runs google chrome like a boss. It takes only 55 seconds to open google, and can hoild up to 4 tabs before crashing. I hope you can help me, Thank you for everything.
