DrawRectangle
From King Arthur's Gold Wiki
Draws a rectangle with a shape specified by the given rect.
As this is GUI-related it is client only - it should be wrapped in "if ( getNet().isClient() )" or be in a client-only script.
This method is part of the GUI namespace so you need to prefix calls to it with 'GUI::'.
This method has two variants. They both specify the shape with a rect, but one also specifies the colour of the rectangle with an SColor argument.
void GUI::DrawRectangle(const recti &rect) void GUI::DrawRectangle(const recti &rect, SColor color)
