Hi all,

I am making a simulation game. How to make ambient vehicle switches from using a partially simulated physics model (or non physics entity) to a fully simulated physics model ?

Did anyone try it before ? Please help me, if you have some tutorials or important links?

just turn it off for as long as it's nit used
phent_enable(me, 0); // 0/1 to turn it on/off
have fun ^_^

Hi dennis,

You said me before you have did it. Please make some tutorials, a lot of people will appreciate it.

dont really have the time right now *not now, and not soon either*
schools very busy for me, and i got my own projects running..
i once made a tutorial and nobody as far as i heard really made use of it, so it seems i aint good on that part as well, i'll leave that to the pro's i'll just help people out when asked for

regards,

Here is my attempt :

function AI_Event()
{ if(event_type == event_impact)
{ if(you) && (my.ObjectID==3) && (you.ObjectID==3)
{ if(my.is_ph==0)
{ ent_playsound(my,ai_horn_wav,100);
phent_settype( my, PH_RIGID, PH_BOX );
phent_setmass (my, 100, ph_box);
phent_setgroup (my, 2);
phent_setfriction (my, 20);
phent_setdamping (my, 20, 30);
phent_setelasticity (my, 30, 10);
//phent_addforcelocal(my, vector(600, 0, 0), you.x);
my.is_ph=1;
}
//sleep(5);
//phent_settype( my, 0, 0 );
//my.is_ph=0;
}
}
.....
.....
function AI_Car()
{ my.is_ph=0; my.ObjectID=3;
my.enable_entity = on;
my.enable_impact = on;
my.event = AI_Event;
....
}

dunno if it matters, but i think the second if was wrong...

should be: if((you) && (my.ObjectID==3) && (you.ObjectID==3))
you forgot the brackety thingys:P

i am gonna take a closer look to this...
regards,

try this else:

Code:

---

 
function AI_Event()
{
	phent_settype( my, PH_RIGID, PH_BOX ); 
	phent_setmass (my, 100, ph_box); 
	phent_setgroup (my, 2);
	phent_setfriction (my, 20); 
	phent_setdamping (my, 20, 30);
	phent_setelasticity (my, 30, 10);

	phent_enable(my, 0);
	
	if(event_type == event_impact) 
	{ 
		if((you) && (my.ObjectID==3) && (you.ObjectID==3))
		{ 
			if(my.is_ph==0)
			{ 
				ent_playsound(my,ai_horn_wav,100);
				
				phent_enable(my, 1);
				//phent_addforcelocal(my, vector(600, 0, 0), you.x); 
				my.is_ph=1;
			} 
		//sleep(5); 
		//phent_settype( my, 0, 0 );
		//my.is_ph=0;
		} 
	}
}

My attempt is working, but not longer. After several collisions it is crashing.

In my city, now all cars are not physics car and there are moving using c_move.

At the collissions of two non-physics entities, i am converting one car to physics car (car who has received impact). And it is working, but not longer.

I think it is better :
Code:

---

  

function AI_Event()
{
  // Check collision and ENABLE it
}
function AI_Car()
{ 
  // create physics entity
  // disable it 
....
}

But, how about FPS if level has too many DISABLED physics entities ?

you should more worry about FPS if everything is ENABLED...
but practise makes perfect, just toy around with that...
maybe you could make a code that if your like 1000 quants away from the player it will get removed, or turned off again??

good luck on it.
