RedM Flags Reference

Flags determine how objects and entities behave within the game world. This reference sheet provides a categorization of commonly used flag values for YMAP and YTYP configuration files.

YMAP Flags

YMAP flags are applied to specific entity placements in the world.

Flag Value	Description
1572897	Default Flag - Standard entity placement.
1572865	Interactable Door - Enables door movement for opening/closing.
536870912	Rotating Objects - Allows objects to rotate (e.g., fans, windmills).

YTYP Flags

YTYP flags define the properties of an archetype (the "blueprint" for an object).

General Flags

Flag Value	Effect
0	Default - No special effects (Stops rainfall if object has bounds).
32	Embedded Collision - Object uses collision data embedded in its model.
8190	Shadow Only - Object is invisible but still casts a shadow.
8192	Emissive/Ground - Does not cast shadows (common for ground textures).
16384	Invisible (Active) - Object is invisible, but collision remains active.
8388608	Ghost Object - Invisible, but collision works and it casts shadows.
33554432	Same effect as 16384 (Invisible with active collision).

Structural & Interaction Flags

Flag Value	Typical Use Case
604110848	Standard Door configuration.
537001984	Alternative Door configuration.
67239936	Special Interaction Door (often used with specialAttribute).
353894400	Stairs and Building Shells.
536870912	General Buildings.
85459202	Seating (Chairs, Benches).

Door Special Attributes

When working with door flags (specifically 67239936), the specialAttribute value determines the animation/movement type.

4	Sliding Door - Opens horizontally (left/right).
5	Garage/Overhead - Opens vertically 90 degrees.
7	Swing Door - Standard door that is pushed/pulled by the player.
