Oh my god, I just was looking through the Teledoor script to make my Security Camera script and this is what i saw --- Code: --- getSubStr(sha1(%obj.getTransform()), 0, 5); --- End code --- Am i late or what :o |
| MegaScientifical:
I don't understand what you need help with. Could you rephrase the question? It probably just adjusts the numbers a little to be more normal, probably insignificant. |
| Uristqwerty:
Sha1 is a cryptographic hash. In this case, it is using the first 5 characters of a hash of the position vector, probably as a unique identifier of something. I suspect that it is implemented in the engine and is already used in the updater, so re-using it was the most convenient option, requiring no additional code for an acceptable result. |
| MegaScientifical:
No no, there's no other variables besides the transform in the command. The 0 and 5 are for getSubStr. |

I think this would make more sense if you actually told us more speciffically what the question is, because right now it just looks like your saying that this function exists and that you're surprised. |
