[OPEN-SOURCE] Machinery Modelling Toolkit

[Fabelwesen]

I haven’t done anything in MMT in regards to multiplayer support. In simplest case, where each client simulates their own vehicle, performance should be fine. If you want to do it on the server, regardless of replication details, then couple of things could be improved. Like packing multiple components into a single component and looking at ways to multi thread calculations. Currently the bottleneck on tanks for example, is in amount of components being used. Last time I’ve run performance test, whole physics update multiple time per frame, took roughly the same amount of time that UE4 spends updating transforms of components - which is a lot imho.
In feature versions I want to re-engineer how components are setup. Was working on that already but stopped due to multiple reasons. Like suspension is already split into two classes, a UObject with all Code an component class that wraps it, so one can make a component with array of suspension stacks instead of having one component per each suspension. Need to do the same for friction component.

Makes sense yes. I guess that, in theory, it’d be possible to leave the clients to their own devices and just have the server check if they are in an invalid location or moving too fast perhaps? I got bored as well, so I started building a version of A_TrackedVehicle in C++ to both learn how you do things and to see what I could do with it since I seem to think better in raw code when the blocks get huge and full of math.

Out of curiosity, since you’re evident quite bright when it comes to these things, have you muddled at all with the PhysX implementation? Frankly I prefer the way you do things due to simplicity and UE’s vehicle physics are “interesting”.
