枚举

enum ComparisonType:

ComparisonType CTYPE_SCALAR = 0

A floating-point scalar.

ComparisonType CTYPE_SCALAR_INT = 1

An integer scalar.

ComparisonType CTYPE_SCALAR_UINT = 2

An unsigned integer scalar.

ComparisonType CTYPE_VECTOR_2D = 3

A 2D vector type.

ComparisonType CTYPE_VECTOR_3D = 4

A 3D vector type.

ComparisonType CTYPE_VECTOR_4D = 5

A 4D vector type.

ComparisonType CTYPE_BOOLEAN = 6

A boolean type.

ComparisonType CTYPE_TRANSFORM = 7

A transform (mat4) type.

ComparisonType CTYPE_MAX = 8

Represents the size of the ComparisonType enum.

enum Function:

Function FUNC_EQUAL = 0

Comparison for equality (a == b).

Function FUNC_NOT_EQUAL = 1

Comparison for inequality (a != b).

Function FUNC_GREATER_THAN = 2

Comparison for greater than (a > b). Cannot be used if type set to CTYPE_BOOLEAN or CTYPE_TRANSFORM.

Function FUNC_GREATER_THAN_EQUAL = 3

Comparison for greater than or equal (a >= b). Cannot be used if type set to CTYPE_BOOLEAN or CTYPE_TRANSFORM.

Function FUNC_LESS_THAN = 4

Comparison for less than (a < b). Cannot be used if type set to CTYPE_BOOLEAN or CTYPE_TRANSFORM.

Function FUNC_LESS_THAN_EQUAL = 5

Comparison for less than or equal (a <= b). Cannot be used if type set to CTYPE_BOOLEAN or CTYPE_TRANSFORM.

Function FUNC_MAX = 6

Represents the size of the Function enum.

enum Condition:

Condition COND_ALL = 0

The result will be true if all of component in vector satisfy the comparison condition.

Condition COND_ANY = 1

The result will be true if any of component in vector satisfy the comparison condition.

Condition COND_MAX = 2

Represents the size of the Condition enum.

属性说明

Condition condition = 0

Extra condition which is applied if type is set to CTYPE_VECTOR_3D.

Function function = 0

A comparison function. See Function for options.

ComparisonType type = 0

The type to be used in the comparison. See ComparisonType for options.
