vis_flags var (atom)

Default value

0

Possible values

• Any combination of:
• VIS_INHERIT_ICON: Use the parent object’s icon.
• VIS_INHERIT_ICON_STATE: Use the parent object’s icon_state.
• VIS_INHERIT_DIR: Use the parent object’s dir.
• VIS_INHERIT_LAYER: Use the parent object’s layer.
• VIS_INHERIT_PLANE: Use the parent object’s plane.
• VIS_INHERIT_ID: Use the parent object’s identity, so it acts like part of the same object.
• VIS_UNDERLAY: Act as if this is at the bottom of the parent’s underlays list instead of overlays (only relevant if using VIS_INHERIT_LAYER or a FLOAT_LAYER).
• VIS_HIDE: Do not show this object in visual contents at all.

This is a set of flags that determine how this object will behave when it is in another object’s visual contents.

Because only turfs, objs, and mobs can be in visual contents, this var belongs only to those types.

The VIS_INHERIT_ID flag effectively makes this object act like an ordinary overlay when in visual contents. This means its mouse_opacity will be meaningless, for example.

Sometimes it’s desirable for an object not to show up in visual contents, so VIS_HIDE will prevent that. The flag applies even if this object appears indirectly, like if it’s in the contents of a turf that is in the visual contents of something else.

Note

Using any of the the flags VIS_INHERIT_ICON, VIS_INHERIT_ICON_STATE, VIS_INHERIT_DIR, or VIS_INHERIT_ID will cause movable atoms to inherit the “moving” flag of their container that appears during gliding. E.g., if your mob is walking, anything in its visual contents that uses these flags will use a moving icon state instead of a non-moving icon state, when available.
