In this section, I will explain you all the features of this tool, panel by panel.

Initialization

• You need to select a DungeonInstance Actor from your scene. The grid will be generated for this actor.
• Then you need to select a size for the generated grid. The size can't be changed after the generation of the grid, so be careful.
• You can also choose a size and a height for the cells.
• Then, you need to choose a BuildingLogic class. This BuildingLogic is an Object which will process the spawning od content inside cells. You can create your own Building logic in Blueprint.
• Once all those steps are done, click on the Init button to generate the grid.

Layout Settings

Add tags, categories, layers so that they can appear in the drop down lists in Paint mode and Edit mode.

When you open the Paint panel, this activates the paint tool. This allows you to "paint" the cells on the grid.

Painting shortcuts :

• Left mouse button => Paint cells
• Left Shift + left mouse button down => Box selection to pain cells
• Left Shift + Left Ctrl + left mouse button down => Box selection to clear cells
• Left Ctrl + left clic => Clear the cell

Levels

You can create multi floors dungeons easily with this system.

Layers

You can use different layers to paint cells. This can be convenient to spawn multiple things inside a specific cell, or add some kinds of sub-rooms inside an existing room.

The edit section will allows you to select cells.

Then you can either modify those selected cells by clicking on "Edit selected cells", or move/copy them around by holding left-alt and dragging them with the mouse.

Maintaining left-Alt + Left-Shift will duplicate the dragged selection. If you don't hold the left-shift key, the selection will be moved.
