QAngle

QAngle is a C++ class that represents a three-dimensional Euler angle. Each QAngle contains three vec_t ordinates:

• X, for pitch (+down/-up)
• Y, for yaw (+left/-right)
• Z, for roll (+right/-left)

(45,10,0) means 45° down, 10° left and 0° roll.

Note:Z is clamped to +/-50 for player viewangles.

Declaration

QAngle angMyAngle = QAngle(45,10,0);

• The classname QAngle is case-sensitive.
• You could also assign to the X, Y and Z member variables separately.
• The prefix ang (or sometimes just a) identifies the variable as an angle.

Converting to a vector

As there is no specific datadesc keyfield for angles, one chosen in Hammer will arrive as a vector. Its ordinates will represent degrees of rotation and not coordinates so it must be fixed up before use:

QAngle angMyAngle = QAngle(vecFromHammer.x, vecFromHammer.y, vecFromHammer.z);

// Conversion back to a vector, if required
Vector vecDirection;
AngleVectors(angMyAngle, &vecDirection);
