Hi,i am using 3dgs(trial version)for now, and currently working on a driving simulator.
i found a tutorial at "aum64" about how to use "car project" template to create racing games using the built-in physics engine .
-in Wed choose map properties >>new script>> "Car_Project" .
-add a car body model then assign PlCar01 action, then add four wheels assign the actions PlCar01_WheelFL , PlCar01_WheelFR, PlCar01_WheelRL and PlCar01_WheelRR .
-save the level, build it and run it.
In A7 it worked very well,but when i tried to do the same at A8 i could not cause A8 is diffrent.
so i tried to find an alternative way, here what i did :
-in Wed choose map properties >>new script>> "template_Project" .
choose "project manager" then add :
car.h,camera.h,car_ai.h,and car_props.h .
-add a car body model then assign the action "car_player".
copy a wheel model to the same folder.
-then add this code to my program script:
#include <ackphysX.h>
function physX_level_load()
{ if (level_ent)
pXent_settype(level_ent,PH_STATIC,PH_POLY);
for (you = ent_next(NULL); you; you = ent_next(you))
{
if (you.emask&DYNAMIC) continue; // only register static ents
if (you.flags&PASSABLE) continue; var type = ent_type(you);
if (type >= 2 && type <= 5) // blocks, models, or terrain
pXent_settype(you,PH_STATIC,PH_POLY);
}
}
function physX_ent_remove(ENTITY* ent)
{ if (ent.body) // unregister entity before removal
pXent_settype(ent,0,0);
}
function physX_open()
{ physX_load();
pX_setsteprate(60,8,0);
pX_setunit(1/40);
on_exit = physX_destroy;
on_level_load = physX_level_load;
on_ent_remove = physX_ent_remove;
while(1) {
physX_run(time_step/16);
wait(1);
}
}
-save the level and script, build it and run it.
the result :the car does not move.
only the car's rear wheels moves in its place (rotate) and the front wheels moves to the right and left.
if anyone know how to fix this problem, please tell me ...
