The ViewMatrix is used for this. It's a structure (much like RefDef structure but this just stores your Viewangles.)
Here's how it looks:
Code:
typedef struct tViewMatrix
{
float AngleOfImpactX; //X Angle Of Impact
float AngleOfImpactY; //Y Angle Of Impact
float PlayerVelocity; //Speed Of Player
vec3_t WeaponPunchAngles[3]; //Angles at which the weapon moves as it fires
float weaponViewAngleY; //The View Angle Of Your Weapon In Terms Of The X-Axis
float weaponViewAngleX; //Same as the above but in terms of the Y-Axis
vec3_t weaponSway; //Vector Holding the Sway Movement of the weapon
vec3_t viewAxis[3]; //The 3D Location Of the View
vec3_t weaponOrigin; //3D Origin Of the weapon
}ViewMatrix_t;
I believe what you're asking is how do you translate a 3D (Y, X & Z) Co-Ordinate to a 2D (Y & X)?
If I could only find the post @
MarkHC did describing it...
But I'll try to explain it....
Lets say we have a vector containing the enemies head location.
Vector3 EnemyHeadLoc;
To Transform it to 2D:
Code:
VectorSubtract ( EnemyHeadLoc, RefDef->CurrentOrigin, CalculatedPos ); //Subtract RefDef's Origin From The Bone's (Head) Location
VectorAngles ( CalculatedPos, VectorAngle ); //Convert the Vector To Angles and store it in VectorAngle (Now Z Angle isn't needed anymore)
* ( float* ) 0x1063898 += ( VectorAngle[ 0 ] -= RefDef->ViewAngles[ 0 ] ) ; //Add the difference of the calculated vector angle minus the current view angle to the ViewAngleX
* ( float* ) 0x106389C += ( VectorAngle[ 1 ] -= RefDef->ViewAngles[ 1 ] ) ; //Same as above but for Y
Here's those function for you:
Code:
void VectorSubtract ( float* v1, float* v2, float* out ) {
out[0] = v1[0] - v2[0];
out[1] = v1[1] - v2[1];
out[2] = v1[2] - v2[2];
}
void VectorAngles ( const float value1[3], float angles[3] ) {
float forward;
float yaw, pitch;
if ( value1[1] == 0 && value1[0] == 0 ) {
yaw = 0;
if ( value1[2] > 0 ) {
pitch = 90;
} else {
pitch = 270;
}
} else {
if ( value1[0] ) {
yaw = (float)( atan2 ( value1[1], value1[0] ) * 180 / M_PI );
} else if ( value1[1] > 0 ) {
yaw = 90;
} else {
yaw = 270;
}
if ( yaw < 0 ) {
yaw += 360;
}
forward = sqrt ( value1[0] * value1[0] + value1[1] * value1[1] );
pitch = (float)( atan2 ( value1[2], forward ) * 180 / M_PI );
if ( pitch < 0 ) {
pitch += 360;
}
}
Aimbot (mouse movement)
fine.
