+This requires some basic knowledge of the shader editor and different variable types!
+
+ Into the meat and potatoes of the version 7 update.
+ These blocks help the user interact with the shaders they made in the pen+ shader editor.
+ The blocks are extremely powerful but harder to use, so you might want to read a tutorial.
+
+
+
Basic UI navigation
+
Opening the editor
+
+ Opening the editor is as simple as hitting the "Shader Editor" button under Advanced -> Custom Shaders.
+
+
+
+ Upon opening the shader editor you will be greeted with another version of scratch!
+ Though this version of scratch has some unique differences.
+
+
+
The top bar.
+
+ First things first the top bar should be elaborated upon.
+
+ The buttons on the left side of the screen will be used the most, so make sure to pay attention to this part.
+
+
+
+
+ The button with the legally distinct cat on it will close the shader editor.
+ Remember there will be a warning before closing the editor, So always save before quitting!
+
+
+ The gear button is your options drop-down. Which will let you turn on dark mode and configure some settings for the editor, like auto compilation and block colors.
+
+
+ The middle icon which will be called the terminal icon will hide/show the stage and variable pane.
+
+
+ The badge is just a credits screen for the shader editor showing contributors and testers.
+
+
+ The final one, which has a floppy disc as it's icon, shows your file management options.
+ Exporting and Importing allow you to edit and save shaders to your project!
+
+
+
+ On the other side of the top bar is a mode switcher. This allows you to switch between the Scratch and GLSL editors.
+
+
+
+
Back to actual scratch!
+
+ "shaders in project"
+
+
+
+ Returns an array that contains a list of the project's shaders.
+ An example would be ["Shader 1", "Shader 2"]
+
+
+
+
+ "Draw triangle and square"
+
+
+
+ Acts the exact same as the draw triangle, and stamp pen square blocks. Except for the fact that is uses your custom shader.
+
+
+
+Shader variables are shader dependant. So multiple shaders can have the same variable names but different values!
+
+ "Set uniform to value"
+
+
+
+ These blocks are lumped together due to the simple fact that they have a similar function but have different inputs.
+ They can be broken down based upon type.
+
+
+ Texture : Can be any image or image like object inside of Pen+, Scratch, or Any Addons.
+
+
+ Numbers : A simple one dimensional number. Depending on the variable's type it can have decimals.
+
+
+ Vectors : Multi Dimensional numbers that can be used for 3d and 2d effects.
+
+
+ Matrix : 2 Dimensional Numbers that are layed out on a grid. Typically used for cameras and transforms.
+ Can either be set from a list or an array.
+
+
+ Cubemaps : 3d textures, Like a skybox.
+
+
+ Of course these blocks have accompanying get uniform blocks.
+
+
+
+
+ "Set array item"
+
+
+
+ Sets the item in the desired array to the desired value! It has a similar typing system to the uniform blocks.
+
+
+
+
+ "Set attribute of point"
+
+
+
+ An attribute is a variable localized to one point of a triangle (sorry square users), these have a similar typing system to uniform blocks.
