Examples
| Description | Prints a vector that represents the angle's upward direction to console. |
|---|---|
| Used on | |
| Code | local MyAngle = Angle(0, 0, 90) print("The upward direction of the angle " .. tostring(MyAngle) .. " is " .. tostring(MyAngle:Up())) |
| Output | The upward direction of the angle 0.000 0.000 90.000 is 0.0000 -1.0000 -0.0000 |
Additional Notes
- To better understand what forward, right, and up vectors are, straighten out your left arm in such a way that it's perpendicular to your body, pointing to something in front of you. This is a forward vector. Now take your right arm and straighten it out as well, except make this arm point to your right. This is a right vector. Now take either arm and point it upwards, so that it's at a 90 degree angle to your other arm. This is an up vector. Note that the direction that your arms are facing changes as you rotate or tilt your body - it is the same way with Angles.
- An angle describes pitch, yaw, and roll. Pitch and yaw can be thought of as the number of degrees that Vector(1,0,0) must be rotated around the y-axis [ Vector(0,1,0) ] and then the z-axis [ Vector(0,0,1) ] (respectively) to equal this angle's forward vector. An angle's roll is an additional value used for spinning things around their x-axis which does not affect a forward vector at all.
