This is a snippet of the blueprint for the custom UMG button widget that is used to make up the grid for this tool. The main event that is acted upon is the on click event, when the button is clicked the public value is incremented. Then modulus on a value equal to the amount of options you want to have is added. Finally if you want the designer to easily differentiate the states of the buttons you can check what the current value is and apply a color to the button in accordance.

This is a snippet of the blueprint for the creation of the grid. To the best of my knowledge you are unable to spawn new actors through a Editor Widget blueprint unless you have reference to an actor that already exists in the world. My hack to this issue was adding all the needed buttons as children of the uniform grid panel, then through code placing them in the correct order. You are able to simulate a 2D array through the use of division for the row and modulus for the column.

This snippet is showing the process for clearing the values in the grid, you are able to make custom events that can be called through other objects (think of them as a public function). When a designer clicks the make layout button that event is called on every button resetting its value to 0 and updating the color of the button.

The actors that are spawned through the grid tool extend the Ramp C++ class that I created. The class uses splines as a reference to spawn boxes along. The spline point positions are determined by the inputted radius and start points. You are then able to change the quality (amount of spline points), ramp Enum (type of ramp: Ramp, Bank, Loop), lambda (distance between spline points), bank (if enum is bank, changes the angle of the bank).

This is a gif of the spawning of the skate park. When the ramps are spawned, they all look the same as the selected ramp. You then have to move them to trigger the construction script, updating the variables in the actor. Once you have spawned the actors you can either destroy all of them or select specific ramps to change their variables.

This gif shows the process of resetting the level you just created. If you feel that you need to restart completely you can very easily do that by pressing the make layout button. Since the references to the ramps you just placed are all stored, the tool is able to destroy the actors easily. Then it goes through the process of setting all the values in the buttons to their default.
