QAngle is a C++ class that represents a three-dimensional Euler angle. Each QAngle contains three vec_t ordinates:
- X pitch +down/-up
- Y yaw +left/-right
- Z 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 justa) 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
AngleVectors(angMyAngle, &vecFromHammer);
