At the moment, the object is emitting fire only while stationary. To reverse this effect (i.e. to have it emit fire only when moving), you need to reverse the Discharge diagram. The X-axis of the diagram is the input values, the Y-axis is the result. Therefore, for input values of 0 (i.e. speed is 0, object is stationary), the Y-axis value should also be zero. When that condition is met, the object won't emit when its standing still because its speed is 0. You can see this setup on the image to the right. |
