Finally I can show some more progress. Most of the latest Onslaught code has been very tough to display.
But the last days have been quite eventful. I tackled one of the bigger classes, the Turret Manager. It should be fully ported, even these fancy things here:
I created an overlay class that I can freely orient to a degree angle and I can set its spread angle. This will be needed for the directional targetting and I will probably also use it for the regular range indicators :)
