Niagara Module Scripts: How do I connect function inputs to a variable in the map get?

Hello,

I’m trying to build a niagara module script, which uses an input curve, similar like the built in scale sprite size module does it.

I created a new input parameter map, but there is no option to connect the curve into a float from curves variable.

What steps do I need to follow to connect the input into my float from curves value?

Hi Robert,

You can configure this as follows:

  1. On the “Parameters” tab (next to the “Input Preview” tab), open category “Module Inputs” and select the desired input (“Curve for Floats” in your screenshot)
  2. On the “Selected Details” tab (on the right), on category “Default Value”, change “Default Mode” to “Custom” using the dropdown.

By the way, there are four modes available to choose from:

- Value: the default value can be set directly in the “Selected Details” tab

- Binding: the default value can be bound to an attribute directly in the “Selected Details” tab

- Custom: the default value is given by connecting a sub-graph to an input pin on the “Map Get” node.

- Fail if previously not set: no default, he value must be set on the emitter stack.

Let me know if this helps, or if you need any further assistance.

Best regards,

Vitor
