Enumerator | |
---|---|
OBJECT_FLAG_NONE | Just nothing. |
OBJECT_FLAG_ONLY_IN_SCENEDIT | Object can only be constructed in the scenario editor. |
OBJECT_FLAG_CANNOT_REMOVE | Object can not be removed. |
OBJECT_FLAG_AUTOREMOVE | Object get automatically removed (like "owned land"). |
OBJECT_FLAG_BUILT_ON_WATER | Object can be built on water (not required). |
OBJECT_FLAG_CLEAR_INCOME | When object is cleared a positive income is generated instead of a cost. |
OBJECT_FLAG_HAS_NO_FOUNDATION | Do not display foundations when on a slope. |
OBJECT_FLAG_ANIMATION | Object has animated tiles. |
OBJECT_FLAG_ONLY_IN_GAME | Object can only be built in game. |
