The DCTestNode is a logic node that returns different types of data based on a user’s selection from a dynamic combo box. It acts as a conditional router, where the chosen option determines which input field is active and what type of value the node will output.

Inputs

Parameter	Data Type	Required	Range	Description
combo	COMBO	Yes	"option1" "option2" "option3" "option4"	The main selection that determines which input field is active and what the node will output.
string	STRING	No	-	A text input field. This field is only active and required when combo is set to "option1".
integer	INT	No	-	A whole number input field. This field is only active and required when combo is set to "option2".
image	IMAGE	No	-	An image input field. This field is only active and required when combo is set to "option3".
subcombo	COMBO	No	"opt1" "opt2"	A secondary selection that appears when combo is set to "option4". It determines which nested input fields are active.
float_x	FLOAT	No	-	A decimal number input. This field is only active and required when combo is set to "option4" and subcombo is set to "opt1".
float_y	FLOAT	No	-	A decimal number input. This field is only active and required when combo is set to "option4" and subcombo is set to "opt1".
mask1	MASK	No	-	A mask input field. This field is only active when combo is set to "option4" and subcombo is set to "opt2". It is optional.

Parameter Constraints:

• The combo parameter controls the visibility and requirement of all other input fields. Only the inputs associated with the selected combo option will be shown and are required (except for mask1 which is optional).
• When combo is set to "option4", the subcombo parameter becomes required and controls a second set of nested inputs (float_x/float_y or mask1).

Outputs

Output Name	Data Type	Description
output	ANYTYPE	The output depends on the selected combo option. It can be a STRING ("option1"), an INT ("option2"), an IMAGE ("option3"), or a string representation of the subcombo dictionary ("option4").
