hey, will you please help me to create a npc in my game? what is the code how to do that? i need it for my game. i dont have any idea to create that because i only a beginner. plzzzzzzzzzzzzzzz
Q: How can I make an entity move to the specified location? A: Here's an example that moves an NPC character towards its goal using primitive, and yet fully functional obstacle avoidance code. ENTITY* goal; action npc_goal() // attach this action to the destination entity { goal = my; } action goal_tracker() // attach this action to your NPC character { while (!goal) {wait (1);} // wait until the goal entity is loaded VECTOR temp, temp_angle; var npc_speed = 5; var covered_dist, i; while (1) { my.skill10 += 6 * time_step; // 6 gives the animation speed vec_set (temp.x, my.x); // trace 10,000 quants below the npc entity temp.z -= 10000; temp.z = -c_trace (my.x, temp.x, IGNORE_ME | IGNORE_PASSABLE | USE_BOX) + 20; // play with 20 temp.x = npc_speed * time_step; temp.y = 0; ent_animate(my, "walk", my.skill10, ANM_CYCLE); covered_dist = c_move (my, temp.x, nullvector, IGNORE_PASSABLE | GLIDE); if (covered_dist < 0.1) // the npc is stuck? { my.pan += 90 - random(180); // then add a random angle to its pan angle i = 0; while (i < 10) // walk in the new direction for 10 frames, play with 10 { c_move (my, temp.x, nullvector, IGNORE_PASSABLE | GLIDE); ent_animate(my, "walk", my.skill10, ANM_CYCLE); i++; wait (1); } } else // the npc can move? Then rotate it towards the goal again! { vec_set(temp_angle, goal.x); vec_sub(temp_angle, my.x); vec_to_angle(my.pan, temp_angle); my.tilt = 0; } if (vec_dist(goal.x, my.x) < 50) // the npc has found the goal entity? break; // then get out of the while loop! wait (1); } // the goal was reached here ent_animate(my, "stand", 0, 0); // switch to "stand" }
