Caspian: A MonoGame Level Editor

This is a level editor for my game made with MonoGame, project named "Pevensie". This level editor is made with Qt6.

(repo: https://github.com/garrdbyrd/MonoGame-Example)

This is made with Qt. This will not have its own dev diary, that is also in Pevensie. It can be built with qmake, edited with your favorite Qt tools.

Disclaimer: I am extremely new to Qt and don't really know how it works.

To-do list

• Implement primary/secondary color system
• Add undo/redo (drag commands; not single tiles)
• Refresh button for tile picker menu
• Open recents
• "Restore defaults" button in preferences tabs
• Fullscreen mainGraphicsView

Harder to-do list

• Implement palette
• Add all standard shortcuts (cut, copy, paste, ctrl + left click, save, etc)
• Autosave functionality
• Implement tabs so the user can edit multiple levels at once
• Export image (.png, .jpg, .tif) (checkbox: ignore default)

Nightmare to-do list

• Read/write proprietary .level and .chunk file types
• Inspect tiles in main graphics view (change properties of particular tiles) (and everything else having to do with the properties menu)

.level Specification

This project utilizes a custom filetype to store/exchange level information. Appropriately, the extension of this filetype is .level. The dot level specification is provided in the following tables:

First kilobyte:

Value	Type	Size	Byte offset	About
Magic Number	uint8[8]	8	0	44 4F 54 4C 45 56 45 4C
Major Version Number	uint8	1	8	Major version number of .level specification
Minor Version Number	uint8	1	9	Minor version number of .level specification
Bugfix Version Number	uint8	1	10	Bugfix/patch version number of .level specification
padding	uint8[5]	5	11	To align timestamp
Timestamp	uint64	8	16	Timestamp of file creation
Level Title	char[128]	128	24	Title of the level
Level Width	uint16	2	152	Number of tiles that span the width of the level
Level Height	uint16	2	154	Number of tiles that span the height of the level
padding	uint8[...]	1024 - padding offset	156	First kilobyte is reserved for file metadata. The size of this padding may reduce as the specification changes and more fields are added above.

Remaining kilobytes:

Each remaining kilobyte corresponds to a tile within the level, which will be specified here as the tile specification is developed.

Value	Type	Size	Byte offset	About
xCoordinate	uint16	2	0	Coordinate of tile on x axis
yCoordinate	uint16	2	2	Coordinate of tile on y axis
uniqueID	uint32	4	4	Unique ID for each tile in the level
tileType	char[128]	128	8	directory/texturename examples: "default/default", "plains/grass"
friction	float	4	136	Coefficient of friction
collision	bool	1	140	Whether or not the tile can be collided with
frictionBool	bool	1	141	Whether or not friction is turned on
padding	uint8[...]	1024 - padding offset	142	Padding

Build instructions:

mkdir build
cd build
qmake ..
make

then run with

./caspian

in the main directory

In order for VS Code to have proper syntax highlighting/"intellisense" via the clangd extension, you must generate compile_commands.json and put it in the main directory.

You'll need to sudo pacman -S bear if you're on Arch, and then

bear -- make
