Spring RTS Engine

Yeah, I had to use bootcamp to play World of Tanks on my Mac.

Oh, interesting. Personally, I've always thought everyone should just ditch Macs and use Windows to make everyone's lives easier but it's good to have options.

Just to make sure, Spring can't be used on Mac, right?

Well.. it is horrible... but the truth is- to get determinism from a computer- you need to sacrifice a cat. So at the heart of spring - is the buildserver, which is connected to a animal farm. Everything goes to false or dominant zero, if a cat dies. The God of Determinism must be pleased for him t...

I think I'll try to create most of the parts from scratch but if there's ever something I hit a wall with, I know I have a great example to look towards. We'll still be here when you realize the magnitude of what needs to be done and give up on your own thing in favor of Spring. We're a caring bunc...

No problem. You guys've been a great help :). I've actually considered using Spring but the thing I want above all is customizability and control over my project so I had to take a different route.

I never said it wasn't. That's why I'm modeling my deterministic engine after Spring's. All the physics will be synced among players which is why I need the same calculations across all platforms. Unfortunately, fixed point math libraries are hard to come by and streflop has no port to C# I can find...

I'm making a deterministic physics engine for my RTS game.

Oh, that's too bad. I'll look into using fixed point math but I can't seem to find a good library in C#.

I was thinking of doing something simple like rounding every calculation to the 4th decimal place. Doubles have up to 16 digits of precision across multiple platforms so (I hope) this will work. Thanks for the wishes and I hope Spring good development as well,

That's alright. I did more research into doubles and conducted some tests. For my uses, it's accurate enough.

Oh, interesting. I think I'll look into using STREFLOP as well. Do you know of any libraries in C#?

Determinism is if the same input is replayed, the same result comes out so the command can be sent instead of positions, as abma suggested.

Oh, I've heard of bullet. Would you use the same technique (streflop) to make it deterministic?

For my game, I'm making it deterministic by using double math.

Thanks a bunch :)

basicly it uses streflop to make all float operations the same on all computers. units don't have to be synced only (user-)commands are transfered between the computers. afaik it doesn't use a collision detection library. Thanks for the info! I'll look into streflop and see if I can do something wi...

Hi, I'm developing an RTS and I'd like to find out how to make simulations deterministic, specifically the physics of it. I noticed that Spring has a really nifty engine so I'd like to learn from it. Does it use an open source collision detection library like Box2D? How does it deal with floating po...
