Hello.

I was wondering how I will be able to rotate a vector up and down and also roll it right or left. I heard about rotation matrices but so far I'm so confused about it.

Multiply the vector by a rotation matrix for the corresponding plane.

so far nothing but fails

PHP Code:

#define Cosine(%1) floatcos(%1,degrees)
#define Sine(%1) floatsin(%1,degrees)

//  ......

        case DRONE_CONTROL:
        {
            static Float:fAngle[2] = {0.0, 0.0};
            fAngle[0] = entity_get_float(ent, DRONE_ROTATION_UPWARDS);
            fAngle[1] = entity_get_float(ent, DRONE_ROTATION_SIDEWAY);
            
            entity_get_vector(ent, EV_VEC_angles, fvAngles);
            
            angle_vector(fvAngles, ANGLEVECTOR_FORWARD, fVector);
            xs_vec_mul_scalar(fVector, fSpeed, fVector);
            xs_vec_add(fVector, fVelocity, fVelocity);

Sorry George but that's not what I needed.

This is what I gave you the link for.

sadly georgik57 this will not going to work cause im not changing only one angle axis. but two its going to differs in which axis is about to pitch and yaws

[Natsheh]

can someone translate this sourcepawn plugin to amxx and get the calculations of how is he doing the rotations.

I made a post where I explained how to use a rotation matrix for rotating a lasermine beam. I can't seem to find it again, but maybe you can.

Well i remember you explained in a post which was by atthar(i am not sure ) his account is banned and all his posts deleted

I was also searching for it
