You know what, you can put it in the fire method, instead. You will just need to add parameters to the ViralLoad constructor so you can pass the returned getArcX and getArcY values.

What did you add?

ViralLoad viralload = new ViralLoad(); addObject(viralload, getArcX(), getArcY()); just that is that all i need to add?

No -- that does not look right. Let me clear something up first. You said:Do you mean a ViralLoad object? But, isn't that the type of object that is fired when the "space" is pressed?

Yes, the viraload and i need both of those things, to shoot when the space bar is pressed and for there to be a viralload where the colors meet in the circlemeter at the top of the arc

Okay, I guess. I would actually suggest to use separate object types for the actual shots and the object that remains at the edge of the circle -- but, so be it. First, the ViralLoad objects will need to know their horizontal and vertical speeds (both being zero for the one at the edge of the circle). These objects also need to retain those values. So, add two int fields to ViralLoad class to hold them. Then add a ViralLoad constructor with two int parameters to acquire the values to be stored in those fields. Next, in the CircleMeter class, add a field to reference the one at its perimeter: Then, add an addedToWorld(World) method to place the load into the world. The load will need to be re-positioned any time degFull changes. Work on that. Respond back when done.

You will not need one in ViralLoad.

viral load circle meter

Now, the fire method in CircleMeter class needs a ref to the rectangle (as shown above), so that, when it creates a new ViralLoad shooting object, it can supply the appropriate axial speeds.
