Coming back to this as it’s still a problem. What I’m trying to do is create a ribbon trail, IDENTICAL almost to Gears-Of-War’s Aim-Trail system. It HAS to be instantaneous, and it has to be every frame. We’re trying to do what Kerbal Space Program does, and predict the orbital path of objects orbiting around each other (using PhysX forces).
We have our calculation for gravity, what we now need to do is simulate this many times every frame for a dummy ‘tracer’ object, and leave behind a trail. I’ve seen a few examples, but most operate on the same time-frame as the object you’re trying to predict and are therefore no use to us. We need instant feedback on where you’re ‘ship’ (or whatever object) will be, and it has to be accurate.
Feel free to throw C++ at me, or if Epic could shed some light on how they did Gears’ aim trails that would be great. I can get Gears of War UScript source files, but it’s a nightmare to pull apart and I never did any UScript, so I figure I’d have a hard time making sense of it.
