Is there a better way to do these ?

Here's some messy code ....

Code:

   if (pBot->strafe_left_time > gpGlobals->time)

   {

        pBot->f_move_speed = 0.0;

        pBot->f_sidemove_speed = -pBot->f_max_speed;

   }

   if (pBot->strafe_right_time > gpGlobals->time)

   {

        pBot->f_move_speed = 0.0;

        pBot->f_sidemove_speed = pBot->f_max_speed;

   }

   if (pBot->move_front_time > gpGlobals->time)

   {

        pBot->f_move_speed = pBot->f_max_speed;

        pBot->f_sidemove_speed = 0.0;

   }

   if (pBot->move_back_time > gpGlobals->time)

   {

        pBot->f_move_speed = -pBot->f_max_speed;

        pBot->f_sidemove_speed = 0.0;

   }

   if (pBot->north_east_time > gpGlobals->time)

   {

        pBot->f_move_speed = pBot->f_max_speed;

        pBot->f_sidemove_speed = pBot->f_max_speed;

   }

   if (pBot->south_east_time > gpGlobals->time)

   {

        pBot->f_move_speed = -pBot->f_max_speed;

        pBot->f_sidemove_speed = pBot->f_max_speed;

   }

   if (pBot->north_west_time > gpGlobals->time)

   {

        pBot->f_move_speed = pBot->f_max_speed;

        pBot->f_sidemove_speed = -pBot->f_max_speed;

   }

   if (pBot->south_west_time > gpGlobals->time)

   {

        pBot->f_move_speed = -pBot->f_max_speed;

        pBot->f_sidemove_speed = -pBot->f_max_speed;

   }

I think these dont need to explain

And the real messy ...

Code:

   Vector v_direction = pBot->waypoint_origin - pEdict->v.origin;

 

   Vector bot_angles = UTIL_VecToAngles(v_direction);

 

   int yaw = pEdict->v.ideal_yaw;

 

   while (yaw <= 0)

        yaw += 360;

 

   while (bot_angles.y <= 0)

        bot_angles.y += 360;

 

   int angle = yaw - bot_angles.y;

 

   while (angle > 180)

        angle -= 360;

 

         bot_angles = UTIL_VecToAngles( v_direction );

 

          UTIL_MakeVectors( pEdict->v.v_angle );

   

   // Check for correct angle and strafe for the correct direction

   // Waypoint at front 

   if ((angle >= 0) && (angle < 22.5) ||

        (angle <= 0) && (angle > -22.5))

   {

        pBot->move_front_time = gpGlobals->time + 1.0;

   }

   // Waypoint at north-east

   else if ((angle >= 22.5) && (angle < 67.5))

   {

        pBot->north_east_time = gpGlobals->time + 1.0;

   }

   // Waypoint at right

   else if ((angle >= 67.5) && (angle < 112.5))

   {

        pBot->strafe_right_time = gpGlobals->time + 1.0;

   }

   // Waypoint at south-east

   else if ((angle >= 112.5) && (angle < 157.5))

   {

        pBot->south_east_time = gpGlobals->time + 1.0;

   }

   // Waypoint at back

   else if ((angle >= 0) && (angle > 157.5) ||

        (angle <= 0) && (angle < -157.5))

   {

        pBot->move_back_time = gpGlobals->time + 1.0;

   }

   // Waypoint at north-west

   else if ((angle <= -22.5) && (angle > -67.5))

   {

        pBot->north_west_time = gpGlobals->time + 1.0;

   }

   // Waypoint at left

   else if ((angle <= -67.5) && (angle > -112.5))

   {

        pBot->strafe_left_time = gpGlobals->time + 1.0;

   }

   // Waypoint at south-west

   else if ((angle <= -112.5) && (angle > -157.5))

   {

        pBot->south_west_time = gpGlobals->time + 1.0;

   }

   BotFixIdealYaw(pEdict);

These code is quite easy to understand , but , Is there a better way to do all these stuff ?

Re: Is there a better way to do these ?

Yes

Easy way (but not human-like IMO): separate body angles and view angles - that's what 99% of the bot makers do.

Or if you want to continue that way, decrease the movement times. Putting gpGlobals->time + 1.0 means that as long as the waypoint will be in that particular direction, the bot will keep pressing that key, but also as soon as the waypoint turns to be in another direction, the bot will still be pressing the same key for 1 second. Reduce that to 0.2 or 0.1 second (depending on your frame time). You can use these values as reaction times too, like I do.

Some examples ? I'm quite a n00b so please dont blame me on that :(
Is it like the PODBot navigation ?

Forget to tell you , I keep track the current waypoint distance from the bot , once it reach a specific distance , I reset all those strafing time to zero so there wont be much problem , but the biggest problem I have with this code is , the strafing is not accurate , like angle between "22.5" and "67.5" are consider as "north-east" and the bot may will strafe not very well :(
