float osVecMagSquare(vector a)
| |
| returns the square of the magnitude of vector a. This saves a square root math operation that is relative slow, when is not needed. | |
| Threat Level | ignore is unknown threat level |
| Permissions | Use of this function is always allowed by default |
| Extra Delay | 0 seconds |
| Example(s) | |
// // osVecMagSquare Script Example // Author: djphil // default { state_entry() { llSay(PUBLIC_CHANNEL, "Touch to see osVecMagSquare usage."); } touch_start(integer number) { vector input = <1.0, 2.0, 3.0>; llSay(PUBLIC_CHANNEL, "The square root of the magnitude of " + (string)input + " is " + (string)osVecMagSquare(input) + "."); } } | |
