A comparison function for common types within the visual shader graph. Compares [code]a[/code] and [code]b[/code] of [member type] by [member function]. Returns a boolean scalar. Translates to [code]if[/code] instruction in shader code. Extra condition which is applied if [member type] is set to [constant CTYPE_VECTOR]. A comparison function. See [enum Function] for options. The type to be used in the comparison. See [enum ComparisonType] for options. A floating-point scalar. A 3D vector type. A boolean type. A transform ([code]mat4[/code]) type. Comparison for equality ([code]a == b[/code]). Comparison for inequality ([code]a != b[/code]). Comparison for greater than ([code]a > b[/code]). Cannot be used if [member type] set to [constant CTYPE_BOOLEAN] or [constant CTYPE_TRANSFORM]. Comparison for greater than or equal ([code]a >= b[/code]). Cannot be used if [member type] set to [constant CTYPE_BOOLEAN] or [constant CTYPE_TRANSFORM]. Comparison for less than ([code]a < b[/code]). Cannot be used if [member type] set to [constant CTYPE_BOOLEAN] or [constant CTYPE_TRANSFORM]. Comparison for less than or equal ([code]a <= b[/code]). Cannot be used if [member type] set to [constant CTYPE_BOOLEAN] or [constant CTYPE_TRANSFORM]. The result will be true if all of component in vector satisfy the comparison condition. The result will be true if any of component in vector satisfy the comparison condition.
