Thought I would make my own thread for this because I seem to be making a obvious mistake. I cant find an answer anywhere so others must not be making this mistake

I have a player I added physics to. I used the same method as was posted in another thread:

action myplayer()
{

myplayer = me;

ph_setgravity (vector(0, 0, -386));
phent_settype (myplayer, PH_RIGID, PH_BOX);
phent_setmass (myplayer, 3, PH_BOX);
phent_setfriction (myplayer, 80);
phent_setdamping (myplayer, 40, 40);



while (1)
{
if(key_w)
{

myplayer_speed.x = 5 ;
myplayer_speed.y = 0 ;
myplayer_speed.z = 0;
phent_addvelcentral (myplayer, myplayer_speed);
}
wait(1);
}

The problem is my player falls over. Then he just tumbles around. Is this in my model? Is there a setting I am missing?
How do I keep him standing upright?

Any help is most appreciated.

wait a sec..

action myplayer()
{

myplayer = me;
myplayer.fat = on;
myplayer.narrow = on;
c_setminmax(myplayer);

phent_settype (myplayer, PH_RIGID, PH_BOX);
phent_enable( myplayer, 1 );
ph_setgravity (vector(0, 0, -386));
phent_setmass (myplayer, 3, PH_BOX);
phent_setfriction (myplayer, 80);
phent_setdamping (myplayer, 40, 40);



while (1)
{
if(key_w)
{

myplayer_speed.x = 5 ;
myplayer_speed.y = 0 ;
myplayer_speed.z = 0;
phent_addvelcentral (myplayer, myplayer_speed);
}
wait(1);
}

no change. He still falls over and when I hit w he just rolls forward bouncing everywhere.

could it be my terrain, should it be registered as a physics object?

nope and i have no idea for this..

btw,what is ur terrain look like?

edit:try delete "phent_setdamping (myplayer, 40, 40);"
and what is ur Gamestudio Version/Edition?

Players and Physics = Bad idea.

But if you want to try, what you'll want to do is recenter your model around it's feet. The physics engine should then use that as the center of gravity.

Another technique I've found useful is to modify the bounding box to be a flat "tile" low on the feet. This way, the model visually will stand tall and walk, but physically will be a flat tile gliding on the ground.

So I don't think anything is wrong with your code or your model... it's just that your model may be "top heavy" and thus the physics engine is just doing it's job.

its got to be something i am doing wrong or just lack of thought put behind the idea that people will use tall humanoid models in the physics system. I put a huge cylinder base on my model and he still flips around and tips over.

Maybe I wont use physics. Seems to be too much trouble. i would of assumed there would have been a special physics setting for player models.

Well back to the drawing board. Thanks for the help.

AFAIK, nobody does for the reasons you've encountered. However, if you read my post, you'll note that IMO your code is right for the physics engine is just doing what it's supposed to do: Physics!

Oh, and there are ways of doing it as I've stated above... you have to work with physics, not against it.

i understand that, but this is just one character, I can only imagine how bad it will get when i start adding lots of movable models. I am developing a isometric Sci-Fi RPG so Physics are not that important. Just a nice additive.

The 3dgs physics are nice and I am not complaining. Just wish the had a scripting command like phent_sethumanoid (myplayer); to tell the engine its a biped and to set the gravity properly. Guess we cant have our cake and eat it too

edit: whats the best method to simulate gravity without the use of physics? To keep the player on the terrain and to fall? Just a constant -z?
