Hey, I am quite new to the a6 physics engine, just now I am deciding to pick it up. My question is : What would simple player physics look like? I'm sure that they would be more powerful than standard physics, right? Does anyone have any examples?

physics engines aren't very suited for bipeds controlled by the player. it's better to script that with commands like vec_accelerate...

Why aren't physics engines suited for players? Can they only handle a one-frame model?
I'm asking this because I scripted a player moving as usual, then being pushed by a normal ent_move - ball, then changing into a ph-entity himself bouncing around, then changing back into a normal entity ready to be pushed again, in a nutshell: a player constantly changing between the states of a usual and a physics entity.
The point is: the engine breaks down after some time of changing back and forth. If I define the player as watched=my, it breaks with the first hit even. No warning message given.
Are there tricks of how to combine moving models and the ph-engine though?

Nadester,u can try it urself by downloading them,it is very great i must tell u,but i still dont know how to implement the physic in game:p some say ent_move cant be used?but i really like the physic engine especially ball part,the ball bounce and perform a realitic projectile motion(i working on my own projectile code:p)

Answer:

I don't have an example because, right now, I don't think it's possible - but here's what I think player physics might look like.

Use the example of your standard shooter. Imagine you are creeping through a room when suddenly you hear an explosion and then your body (and viewpoint) are slammed to the left, striking the wall and coming to a sudden stop. If player physics were possible I could see them used in this way to react to a force (e.g. bullet, weapon) striking the player. A 2nd example is if you're shot in the right shoulder from in front, and then the player and viewpoint spin to the right and fall back some.

You can see the ragdoll example in the Newton Game Physics exhibiting this type of behavior, but right now, the ragdoll is not the player. Basically, though, the player's body would react realistically to outside forces.

The only possibility I see now is a method of propelling the player with an impulse instead of the current technique of using movements.

download the demo,interactive demo can help you get better understanding:p

In my project, everything is physical, players included. Here, the player arrows control the magnitude and direction of a skill named net_force_x, net_force_y, and net_force_z. These skills are then processed by an while/wait update routine that applied a phent_addlocalforce in accordance to the player intentions. I use a multiple combination of simultanous forces for stablity instead of just one force on the players center. Furhtermore, I had to make sure that my forces where PULLING (ie applied in front of the entity) instead of PUSHING (applied from behind) in order to increase biped stability. At low speeds and accelerations (around 500 quants/s and 50 quants/s/s), this configuration and the player movement is stable. Any higher and he becomes unstable.

It's pretty nice to have player collision controlled by the PE. It looks damn tight and when you slam into a bunch of static looking barrels, they, being physical too, respond in kind.

IMHO therefore, while the current PE is not optimal for bipeds, it can be done and it looks damn slick!

I think your problems may also have to do with registering and unregestering physical entities. I too have had (unrelated?) problems with the physics engine focusing on the registering of physics ents.

to bad i am using a5.5:p it doesnt recognize the command to implement the physic in script:p i get a6 later:p

The newton engine is free (?) and is compatable with A5 (?). I put question marks cause I'm not 100% sure on both those facts, but if you want physics without the 3DGS PE, you should look at the Newton Physics Engine threads.
