<member name="hint" type="int" setter="set_hint" getter="get_hint" enum="VisualShaderNodeScalarUniform.Hint" default="0">
A hint applied to the uniform, which controls the values it can take when set through the inspector.

<member name="max" type="float" setter="set_max" getter="get_max" default="1.0">
Minimum value for range hints. Used if [member hint] is set to [constant HINT_RANGE] or [constant HINT_RANGE_STEP].

Maximum value for range hints. Used if [member hint] is set to [constant HINT_RANGE] or [constant HINT_RANGE_STEP].

Step (increment) value for the range hint with step. Used if [member hint] is set to [constant HINT_RANGE_STEP].

No hint used.

<constant name="HINT_RANGE" value="1" enum="Hint">
A range hint for scalar value, which limits possible input values between [member min] and [member max]. Translated to [code]hint_range(min, max)[/code] in shader code.
