New engine features

pX_stats

This new instruction returns the number of registered physics entities that are currently in the level.

#include <default.c>

#include <ackphysx.h>

var physics_ents;

function main()

{

       physX_open();

       level_load(""); // load an empty level

       vec_set(camera.x,vector(-100, 0, 30));

       pXent_settype(NULL, PH_STATIC, PH_PLANE); // create a static plane at groundlevel zero

       while (1)

       {

               ENTITY* ball = ent_create(SPHERE_MDL, vector(random(100), random(50), 100), NULL);

               pXent_settype(ball, PH_RIGID, PH_SPHERE ); // create a ball

               pXent_setelasticity(ball, 50);

               pXent_addvelcentral(ball, vector(0, 0, 10));

               physics_ents = pX_stats(1);

               wait(-5);

       }

}

PANEL* counter_pan =

{

       layer = 15;

       digits(20, 20, 4, *, 1, physics_ents);

       flags = SHOW;

}

PhysX engine update

GameStudio 8.30 now uses the 2.8.4 PhysX engine; this allows us to deploy physics-based Gamestudio applications without having to install the PhysX System Software on the target system.

inkey_active improvements

The inchar( ) function can now be terminated prematurely by setting inkey_active to 0.

#include <default.c>

STRING* input_string = "";

var code_guess;

function main()

{

       level_load(""); // load an empty level

       while (1)

       {

               code_guess = inchar(input_string);

               // pressed the "Enter" key? (scan code for enter = 13)

               if (code_guess == 13)

               {

                       printf("Honored to serve you, safe cracker");

                       break;

               }

               else

               {

                       printf("Ha ha ha! You'll never break the code!");

               }

               wait (1);

       }

}

function abort_startup()

{

       while (1)

       {

               if (key_q) // the Q ("quit") key was pressed?

               {

                       inkey_active = 0; // don't wait for player's input anymore

                       printf ("Code input aborted");

                       sys_exit (NULL);

               }

               wait (1);

       }

}
