Real-Time Physics Simulation Forum

Hi everyone, I'm writing a server/client game, both server and client use Bullet physics. My server has the 'real' world, and it sends this world to clients. When clients update the server, they send to the server their direction of movement. When the server receives this message, a certain amount o...

You're absolutely right. At first I wanted to choose a partial solution, which I thought would make my life easier. I was wrong. It's partial and harder to implement. What I had before I started this thread was: 1. Server sends world information to client 2. Client sets state according to message <-...

Hi Jyavoc, Thanks for the reply! You can read more about games networking in this article: http://gafferongames.com/networking-for-game-programmers/what-every-programmer-needs-to-know-about-game-networking/ I do something very similar to what you suggested - the client & server decide on their o...

Hi everyone, I'm writing a network game. I would like clients to show their players' location based on what the server sends them. However, due to lag between the server and the client, when the server sends location X in time T to the client, the client should calculate where the player will be in ...

* bump *
does anyone have an idea for this? i'm getting desperate here..

Hi everyone, In my game I'm running Bullet in both server & client. In this game each character has an orientation and state (which is Standing / Walking / Running). A character can only walk forward (forward is defined by the character's orientation). The server receives a state from the client...

from my understanding, setLinearVelocity() is framerate dependent (see here: http://www.bulletphysics.org/mediawiki-1.5.8/index.php/Code_Snippets for example) what i was trying to say is that the character moves faster than the limit when i play around with applyForce(). i didn't encounter a situati...

i guess the reason no one answered is that this post is lacking info; i'll elaborate: if i'll only boost the character when the speed is below the maximum, i'll end up having an object that sprints every few minutes to above the limit, then slowly slows down to the limit, and over again. this isn't ...

Hi everyone, In my game today I'm controlling character movements via setting their linear velocity. From what I read, this isn't ideal because it's affected by the frame rate (and indeed that's what I see). I'm now at a stage I'd like to change this behavior. My requirements are fairly simple (to m...

thanks for the reply! that's what i assumed. thanks for confirming. my world is basically an arena with walls around it and some walls inside it - much like a maze. it could quite easily be divided to several 'wall' objects i guess. the problem is syncing this with the graphics engine, but i guess t...

Hi everyone, I'm trying to create a game using Irrlicht as my graphics engine and Bullet as my physics engine. Assuming I have a map represented in a 3d file format (such as .obj, .3ds), it's fairly easy to load it and draw it using Irrlicht. However, I can't find a way to do it in Bullet. I found t...

thanks a lot for the code snippet!
now i see that you can extract the hit point from the rayTrace callback.

i'll dig in further, but some basic testing i made look very promising. thanks!

if you're not using a real bullet - how do you calculate the impact position? are you applying a force to that position to simulate a bullet hitting it? Thanks! *EDIT* btw, is that video showing open source project? can you by any chance send me the sources so I can learn how to do these cool things?

Hi everyone, I've been playing around with bullet for a few weeks now. I must say that it looks pretty damn good - both easy to use, and seems very powerful and high-performing. Anyway, I'm still in technical demo stage. I'd like to consult on what's the best way to handle bullets (like: gun's bulle...
