TRANSCRIPT

Welcome back, everyone. In this lesson, we're gonna be creating a camera in Godot and having it track our player horizontally. So in our main scene here, I'm gonna create a new node, and this is gonna be of type Camera2D. Now, this Camera2D, as you can see, it appears in our main scene, and it has that blue rectangle similar to the one that already exists. So what we can do is, we can actually have this camera override the existing preset window, which is what we see into the world, by going over to the Inspector with the Camera2D selected and click on Current. Make sure Current is enabled, and you'll see that the blue outline suddenly glows. Now if we press play, you'll see that the camera has changed, but right now, it is not moving to track our player. So in order to do that, let's first of all move our camera over to where we want it to be initially. So we'll drag it--we'll select the camera here, and we'll drag it down to here, where it overlays the existing camera. Might need to move it up just a bit. There we go. And now what we can do is, if we go to the Inspector, we can create a new script for this camera, so we'll go new script here, and I'm gonna rename this to Camera Controller. We'll create that, and here we go. So all we're gonna do in this script right here is two things. We're gonna create a variable. So we'll go onready var player, and this is going to be equal to get underscore node, and we wanna find the player node. Now, to do that, we need to go to the root of our scene, so we'll go slash root slash main scene slash player, and this is gonna find our player node. Then if we go func underscore process delta. Now, this gets called every frame. We just wanna go position dot X equals player dot position dot X, and this will track us along our X position. So if you press play now, you'll see that the camera now tracks us along the X position but the Y stays the exact same like so.
