Character movement & physics

[hayer]

Hi,

I'm in the progress of making a 2d multiplayer platformer. So the question is; how do I get some smooth movement for my actors? Right now I'm using Box2d, but it is very.. "cluncky" and "sloppy". I want more have more control over it. It feels like it takes like hours to just change the maximum movespeed. And that is after I've written nearly 800 lines of "special physics rules" just for the player actor.

So, any tips on what to do? Do I roll my own? Do I change to something like chipmunk?



And yes, I need physics -- if I remove it, it will take too much of the game experience away.

Are you sure you really need a full blown physics engine? Or if all your after is collision detection (running, jumping, falling, colliding into walls, basic platformer stuff) you might want to consider implementing your own system.

Sounds like you need to adjust the velocity that your applying to your character. Yes getting it fine tuned can take some work, but I have never experienced Box2D feeling clunky.

I'm not a Box2D guru, but I think you should show some of this code. As far as I know in Box2D you can define collision callbacks, adjust speed, velocity, and other properties, but I never heard of writing "physics rules". Unless your talking about callbacks that determine if objects collide or pass through each other which would not make your player feel clunky.

Yes, I do. As I also needs barrels rolling, explosions, walls to destroy - Removing this will take away too much from the game. I've already prototyped out explosions, walls that fall apart, the only thing I can't get right is the player movement.

Yea, was late last night. Clunky isn't the right word.

Hello

you need that your character can gain speed gradually, and brake, and jump with parabollic effect, and fall, etc?  like Mario and Sonic?

in my poor Sonic, i already programmed that ... a little tedious ... but it s nice when you succeed

if it s this, then i can give you here the code fragments (i use C#)
