InGame Code Editor is an advanced input field for Unity that makes use of TextMesh Pro to display syntax highlighted code. Much of the inspiration for the syntax highlighting is taken from notepad++ and as a result it is extremely customizable allowing you to add syntax highlighting support for new languages.
Please note that IGCE is an advanced input field and not a fully featured text editor. Features such as menu bars and tool bars will need to be added manually if required.
