Coordin
Coordin is a tool created by 櫛ヶ浜やぎ, which allows the user to easily create rectangle collisions for a ghost. Note that it is entirely in Japanese, but the only text in the program is a simple instruction to drop an image file onto the window.
Usage
Usage is simple; the user can run the program, drag and drop a surface into the window, then drag and drop on the image to draw a box. Once the mouse button is released, the coordinates of the corners of the box will be copied to the user's clipboard. The user may also click on the box and drag it around, and when released, the new coordinates will be copied to the clipboard.
Coordinates are copied as a comma-separated string, which is the format used by surfaces.txt. This enables the user to easily paste the information straight into their shell code.
Images in the program will appear with altered colors; this is normal and has no effect on the output.
