[QUOTE=NovembrDobby;29086576]Does anyone know how to do raw mouse input in C#? I've been having problems with centering the mouse all the time recently.[/QUOTE]

Also, is there a way to do it and still keep it multi-platform?

[QUOTE=Jallen;29086722]So many people don't know about fixed timesteps. They are easy to implement and 100x better so they should really be the norm for framerate independent game logic by now.[/QUOTE]

I think I understand how it works but I'm not sure.
Basically, how I see it is:
Render/sleep/do stuff to pass the time and measure how much time it passed since the last update. Then, while that time is above 1/60, update and reduce the total time by 1/60 per update.

It's more like (considering this is in your loop)
- check elapsed time, add it to the accumulator
- if accumulator < the timestep do nothing
- if accumulator > the timestep then run the update [elapsed time / timestep] times (integer division) and put [elapsed time % timestep] in the accumulator
- render

[QUOTE=ColdFusion;29086766]The problem is that it doesn't work in multiplayer games.[/QUOTE]

You're going to have to explain why, because I see no problem whatsoever in using a fixed timestep for an online game.

Oh, I remember you saying you should render as fast as you can and update once you're above 1/framelock.
But rendering once per update makes sense, yes.

[thomasfn]

In my game, I have an FPS max on (say about 40, it's only a 2D game where FPS isn't so important) - so each frame has a max of 25ms to update (run physics tick and then render). If the actual frame takes, say, 1ms to update, then it will sleep for 24ms and run the next frame. I tell my physics engine to step at 25ms each time, regardless of how long the frame actually takes to update - if the frame takes longer than 25ms to update, then it's either a freeze in the system (like minimising the window, or the OS loading something or something) and the physics won't glitch massively when normal FPS is restored (like Dlaor's ball-flying-through-laser exploit) but simply tick along a 25ms frame like nothing ever happened - which is what you'd expect.

If the frames constantly take longer than 25ms to run, like you're trying to run it on a REALLY old PC, then the simulation will slow down and lag - but I don't care about trying to make my game work on PCs with 100Mhz processors and 32mb of ram.

Rendering faster than updating is pointless, because you're just gonna end up rendering the same frame twice - which is a waste of CPU.

Well you do render as fast as you can in the steps I said.
You could render only once per update but there are also methods of interpolation between updates which stop temporal aliasing, so you wouldn't be able to do it in that situation. (temporal aliasing is an effect of the frametime not matching up well with the timestep that causes the occasional 2 update visual skip)

See my response to darwin.
Also you are forgetting things which won't be dependent on the updates. Visual effects (like fades) which need to be smooth but not accurate may take place using a variable timestep outside of the update function.

Is there a way to get IntelliSense with runtime-compiled files in Visual Studio?

[Robert64]

[QUOTE=Darwin226;29087561]Is there a way to get IntelliSense with runtime-compiled files in Visual Studio?[/QUOTE]

I ended up creating a separate project for them, which required the executable for the main project but was set to not compile but to just copy across to where I wanted my scripting files to be.

[ColdFusion]

If you use a SemiFixed(or fixed) timestep in multiplayer game certain players will be running faster/slower as others?(At certain moments) You can't expect all players to run at the Speed of the SemiFixed timestep.

You could have the physics simulation happen on the server.

[Darwin226]

Well, players that have slower computers that can't keep up with the update will have input lag with any timestep method.
For others, the server should make sure that they don't try to move more times than they're allowed to.

Correct me if im wrong but the Ms-PL is basically the same as the ZLib licence right?
As in "Use it as you want, dont claim you created it and dont hold us responsible if you blow up the world with it" so you can use it in commercial projects?

That's what I'm using at the moment, but the buttons are really dark.

How that hooks anything is beyond me(you never specify 'send' anywhere, at least that I can see). Anyways I use DetourAttachEx instead of DetourAttach. Also I always liked v1.1 better so I created functions like

[cpp]LONG WINAPI DetourFunction(PVOID *ppPointer,
PVOID pDetour)
{
return DetourFunctionEx(ppPointer, pDetour, NULL, NULL, NULL);
}

LONG WINAPI DetourFunction(PVOID *ppPointer,
PVOID pDetour,
PDETOUR_TRAMPOLINE* ppRealTrampoline)
{
return DetourFunctionEx(ppPointer, pDetour, ppRealTrampoline, NULL, NULL);
}

LONG WINAPI DetourFunctionEx(PVOID *ppPointer,
PVOID pDetour,
PDETOUR_TRAMPOLINE *ppRealTrampoline,
PVOID *ppRealTarget,
PVOID *ppRealDetour)
{
LONG error = NO_ERROR;

if ((error = DetourTransactionBegin()) != NO_ERROR)
return error;

if ((error = DetourUpdateThread(GetCurrentThread())) != NO_ERROR)
return error;

if ((error = DetourAttachEx(ppPointer, pDetour, ppRealTrampoline, ppRealTarget, ppRealDetour)) != NO_ERROR)
return error;

if ((error = DetourTransactionCommit()) != NO_ERROR)
return error;

return NO_ERROR;
}

LONG WINAPI DetourRemove(PVOID *ppPointer,
PVOID pDetour,
BOOL remtramp)
{
LONG error = NO_ERROR;

if ((error = DetourTransactionBegin()) != NO_ERROR)
return error;

if ((error = DetourUpdateThread(GetCurrentThread())) != NO_ERROR)
return error;

if ((error = DetourDetach(ppPointer, pDetour, remtramp)) != NO_ERROR)
return error;

if ((error = DetourTransactionCommit()) != NO_ERROR)
return error;

return NO_ERROR;
}[/cpp]
