Game.Tools.AgeMask

Assembly: Assembly-CSharp (game runtime assembly; typical for Cities: Skylines 2 modding)
Namespace: Game.Tools

Type: public enum (flags)

Base: System.Enum (underlying type: byte)

Summary:
AgeMask is a [Flags] enum used to represent one or more age categories as a bitmask (byte) — suitable for tagging or filtering objects by age group (for example trees/plants, citizens, or other age-related systems). Each named value is a single-bit flag so multiple ages can be combined with bitwise operations.

Fields

  • Sapling = 1
    Represents the "sapling" age group. Bit 0 (value 1).

  • Young = 2
    Represents the "young" age group. Bit 1 (value 2).

  • Mature = 4
    Represents the "mature" age group. Bit 2 (value 4).

  • Elderly = 8
    Represents the "elderly" age group. Bit 3 (value 8).

Properties

  • This enum defines no properties.

Constructors

  • Enums do not declare constructors. The default enum value (0) means "no flags set" but there is no named None member in this enum — you can treat (AgeMask)0 as "no age selected" or define your own None if needed.

Methods

  • This enum defines no methods. Use standard enum/bitwise operations or System.Enum.HasFlag for checks.

Usage Example

// Combine flags
AgeMask mask = AgeMask.Sapling | AgeMask.Young;

// Check with bitwise operation (preferred for performance)
if ((mask & AgeMask.Mature) != 0)
{
    // mask includes Mature
}

// Check with HasFlag (convenient but slightly less performant)
if (mask.HasFlag(AgeMask.Sapling))
{
    // mask includes Sapling
}

// Add or remove flags
mask |= AgeMask.Mature;    // add Mature
mask &= ~AgeMask.Young;    // remove Young

// Test for no flags set
bool none = mask == 0;     // or (mask == (AgeMask)0)

Notes: - Because the enum is marked with [Flags], combine values with | and test with & or HasFlag. - The underlying type is byte, so the mask occupies a single byte; expand carefully if you plan to add more categories.
