Does anybody know a tutorial how to use the Engine? Here my test-script (whats wrong? I cant move on key_i/key_l): Quote: function main() { level_load ("Physik.wmb"); wait(2); ph_setgravity (vector (0, 0, -386));//9.81m/s^2 camera.x = - 50; } action model() { phent_settype (my, PH_RIGID, PH_BOX); phent_setmass (my, 3, PH_BOX); while(1) { if (key_i) my.x += 6 time_step; if (key_l) my.x += -6 time_step; wait(1); } } new project in early stage...

Whats wrong? Quote: #include <acknex.h> #include <default.c> //////////////////////////// var speed1; function main() { level_load ("Physik.wmb"); wait(2); ph_setgravity (vector (0, 0, -386)); camera.x = 50; } action model() { phent_settype (my, PH_RIGID, PH_BOX); while(1) { if (key_i) speed1 = 10 time_step; c_move (my, nullvector, vector(0, speed1, 0), NULL); wait(1); } } new project in early stage...

And why dont you read the physics tutorial before you start to script? You have to understand the basics before you can program something. I think spending 10 minutes to read the tutorial page is faster than randomly trying commands and then wondering why it does not work.

I have tried the phent_function but I didn�t get how those work Quote: And why dont you read the physics tutorial before you start to script? oh yes. I have done it but the information you get from it is really a bit too little. Do you know some tut? new project in early stage...

When physics has control over an entity, you can not move it manually. When you want to move it yourself, don't make it a physics object.

The following is my test script for a movement with physics: Quote: #include <acknex.h> #include <default.c> //////////////////////////// VECTOR speed1; function main() { level_load ("Physik.wmb"); wait(2); ph_setgravity (vector (0, 0, -386)); camera.x = 50; } action model() { phent_settype (my, PH_RIGID, PH_BOX); phent_setdamping (my, 80, 80); while(1) { //speed up!// if (key_i && (speed1.x < 50 && (speed1.x >= 0)))//speed up forwards, if speed1 is 0 or higher speed1.x += 0.02; if (key_k && (speed1.x > -10 && (speed1.x <= 0)))//speed up backward, if speed1 is lower than 0 speed1.x -= 0.02; //break!// if (key_i && (speed1.x < 0))//break, if speed1 is lower 0 speed1.x += 0.04; if (key_k && (speed1.x > 0))//break, if speed1 is higher than 0 speed1.x -= 0.04; if (!key_i && !key_k) speed1.x = 0; phent_addcentralforce (my, speed1); //phcon_setmotor//ph_setautodisable//ph_autodisable//ii wait(1); } } new project in early stage...
