Display Traits correspond to the Order and Visibility action menus, and Collisions and Visibility expression menus exposed by many objects, including the Active Objects. These additionally expose Active Object's Scale / Angle action menu. The MMFI is able to determine at runtime without additional help whether an object supports these traits, and will expose the corresponding fields and methods if it does.
Display Fields
These fields can be read from or written to directly
| number | angle | Object's rotational angle, may be integer or float depending on runtime |
| boolean | edgeAA | Whether or not an object's edges are antialiased with the frame |
| number | inkCoef | Coeficient used for some ink effects, e.g. semitransparency |
| number | inkEffect | Object's current ink effect |
| boolean | rotationAA | Whether or not antialiasing is enabled for rotation |
| boolean | scaleAA | Whether or not antialiasing is enabled for scaling |
| number | scaleX | Object's scaling factor on the X axis |
| number | scaleY |
Object's scaling factor on the Y axis |
| boolean | transparent | Whether or not an object's background is transparent |
| boolean | visible |
Whether or not an object is visible in the frame |
Display Fields (Read-Only)
These fields can be accessed, but not updated.
| number | zorder | Object's Z ordering index |
Display Methods
These methods may be called by objects with display traits. They are protected, so they cannot be overwritten. The colon operator, which is used by most Lua object tables, is optional here. Click on each function for more information.
