[Tutorial] Play a cutscene video in your mod!

Before I start, I want to say thank you to Tbroski and Klemen for helping me create this tutorial.

First, have a video ready, best if short and low-res.

Convert it to a PNG image sequence, you can use any service you so desire. (if you have photoshop, follow this tutorial https://ihatetomatoes.net/convert-video-image-sequence)

Then, you get a folder full of your images and name them accordingly. If you have 100 frames for example, name them from 0 to 99.

Go to the "Import Other Textures" section in MCR, and import all of them clicking the first and shift-clicking the last texture

Now to the code part, create a procedure element, and set the trigger to on player tick update.

Go to the code, and add the following:

		Entity entity = (Entity) dependencies.get("entity");
		entity.getPersistentData().putDouble("Frame", ((entity.getPersistentData().getDouble("Frame")) + 1));
		entity.getPersistentData().putString("Location",
				(("yourmodid:textures/") + (Math.round((entity.getPersistentData().getDouble("Frame")))) + (".png")));
		if (((entity.getPersistentData().getDouble("Frame")) >= maxframe)) {
			entity.getPersistentData().putDouble("Frame", 0);
		}

Replace yourmodid with your mod Id and maxframe with your max frame number.

This code snippet will create a Frame variable that increases per tick, and get the location of a frame with that variable.

Next, create an overlay element, select a dummy base texture, lock the code, and change the line of code that binds your base texture to this:

                Minecraft.getInstance().getTextureManager().bindTexture(new ResourceLocation((entity.getPersistentData().getString("Location"))));

Run your mod and you should be seeing a silky smooth video playing, the video will repeat once it reaches the end.

Add sound and customize the code any way you want.
