Define () is a Hat block-like shape that falls under the More Blocks category. It is used to define custom blocks. A define block is created each time a new custom block is, appearing on the Scripts Area
of the current sprite, or the Stage's scripts area if it selected. Deleting a define block is only permitted if there are no instances of the associated custom block in the project.
