Thank you for reading this. My problem is that I can't figure out how to make an entity (the monster bad guy) turn to the player entity and run forward until colliding and if the player moves back the entity moves to the player again. I would like to have a suggestion on code please and if you want me to post my code just say so.I have tried several codes that all don't seem to work. I am working on a school project over the break so I need a bunch of help which any is appreciated.

so what about that error message? what kind of error do you get?

That was an error message that appeared on the game screen and then somehow let the game start anyways when i entered this code for trying to get my problem solved. I apologize for not posting it earlier. Here it is and let me know if u need to see more code or if u can tell what should be done:


action monster_ai()
{
c_scan(me.x,360,vector(360,360,0),IGNORE_ME);
}

action operate_monsters_act()
{
grav_rule_act();
monster_ai();
}

action operate_player_act()
{
stand_player_act();
grav_rule_act();
move_forward_act();
turnl_act();
turnr_act();
camera_folo_func();
move_back_act();
}

function main()
{
level_load("prototype.wmb");
ent_create("player.mdl",vector(150,400,-400),operate_player_act);
ent_create("demon.mdl",vector(300,-1500,-395),operate_monsters_act);
}

Also it said:SYS_CRASH:monster_ai();

at a guess you've got an empty pointer in monster_ai(), post the code for that function and the function that calls it too

set
while(!me) wait(1);
at the beginning of your action.

That obviously wont help because the wait is never executed.

Maybe you havent posted the whole code here, when your c_scan triggers an event on the player and the player is not set up yet that will cause a crash? Check your scan event function.

Or, insert a wait(1) - without the while(!me) - before the scanning, to be sure that the player is set up.

Thank you for that piece of code it got rid of the error message and game works fine however I have a new question. How would you get the monster entity to face my player? I'm trying to get it to where he always runs to the player until colliding. I would appreciate any suggestions and here is all my code:

var walk_perc_var;
var max_hp_var = 100;
var health_var = max_hp_var;

STRING* health_str = "HP - ";

TEXT* health_txt =
{
pos_x = 0;
pos_y = 0;
string(health_str);
font = "ARIAL#18";
flags = SHOW;
}

PANEL* health_pan =
{
digits(32,0,4,"ARIAL#18",1,health_var);
flags = SHOW;
}



action grav_rule_act()
{
while(1)
{
c_move(me,vector(0,0,-2),NULL,GLIDE);
wait(1);
}
}

function camera_folo_func()
{
while(1)
{
vec_set(camera.x,vector(-150,0,150));
vec_rotate(camera.x,me.pan);
vec_add(camera.x,me.x);
vec_set(camera.pan,vector(me.pan,-20,0));
wait(1);
}
}

action stand_player_act()
{
while(1)
{
while(!on_anykey)
{
ent_animate(me,"stand 0",walk_perc_var,ANM_CYCLE);
walk_perc_var += 10 * time_step;
wait(1);
}
}
}

action turnr_act()
{
while(1)
{
while(key_cur)
{
my.pan -= 10*time_step;
wait(1);
}

wait(1);
}
}

action turnl_act()
{
while(1)
{
while(key_cul)
{
my.pan += 10*time_step;
wait(1);
}

wait(1);
}
}

action move_back_act()
{
while(1)
{
while(key_cud)
{
ent_animate(me,"walk",walk_perc_var,ANM_CYCLE);
walk_perc_var += 10 * time_step;
c_move(me,vector(-15*time_step,0,0),NULL,GLIDE);
wait(1);
}
wait(1);
}
}


action move_forward_act()
{
while(1)
{
while(key_cuu)
{
ent_animate(me,"walk",walk_perc_var,ANM_CYCLE);
walk_perc_var += 10 * time_step;
c_move(me,vector(15*time_step,0,0),NULL,GLIDE);
wait(1);
}
wait(1);
}
}

action monster_ai()
{
while(!me)
{
c_scan(me.x,360,vector(360,360,0),IGNORE_ME);
}
}

action operate_monsters_act()
{
grav_rule_act();
monster_ai();
}

action operate_player_act()
{
stand_player_act();
grav_rule_act();
move_forward_act();
turnl_act();
turnr_act();
camera_folo_func();
move_back_act();
}

function main()
{
level_load("prototype.wmb");
ent_create("player.mdl",vector(150,400,-400),operate_player_act);
ent_create("demon.mdl",vector(300,-1500,-395),operate_monsters_act);
}

that is a bunch of actions...try using only 2 actions....

1 for the player, and one for the enemy. if you are going to call on piece of code repeatedly by different entities, like gravity for instance. You can set that in a separate "function" and then call that from the entity actions. If you do not understand what I mean, than you should go through the workshops again....also read the AUM's starting from around 67 or so....I think that is when lite-c was launched...correct me if I am wrong.
