Bug in botmans changepitch function

[Rick]

There is a bug in botmans changepitch function;

 current = pEdict->v.v_angle.x;

should be

 current = -pEdict->v.v_angle.x;

This is because the x angle is reverted...

hmm, i think you are applying here the fix that later on Paulo-la-frite once did? (did i spell his name right?). AS the X axis gets 'fixed' later on

[botman]

The pitch of your view angles (v.v_angle) is inverted from the angle of the vector from your origin to your enemies origin. The view pitch is also 1/3 of the angle between the enemies origin and your origin, thus...

Vector v = (enemy.origin - my.origin);
angle = VectorToAngles(v);
view_pitch = (-1 * angle.pitch) / 3;

I once had made a little sketch that described all this Half-Life angle stuff. Too bad it's gone during the last website tidy-up.

Basically you have to consider the body and the view angles on the X plane as by reference to two vectors that point backwards from each other.

I guess you all mean this code?

 	// set the body angles to aim correctly
 	pEdict->v.angles.x = pEdict->v.v_angle.x / 3;
 	pEdict->v.angles.y = pEdict->v.v_angle.y;
 	pEdict->v.angles.z = 0;
 
 	pEdict->v.v_angle.x = -pEdict->v.v_angle.x; // Aim bug-fix

(For me)This happens after the botchangepitch function.
And since the ideal angle isn't inverted I guess I had to do this, atleast for me it fixed the aiming code

You can invert the pEdict->v.idealpitch and it will be OK.

Of course, the way you are doing seems to work too.
