Am I the only one noticing the fact that using PositionEntity with values over 10000 gets out of wack and appears somewhere totaly different?

That's probably down to floating point accuracy. . . they are only accurate to around 5 or 6 places i think. This means that in the order of 10000 or more you could be off by a few units. . .

Ive used values of over 10,000 for positionentity with no problem...

When you say out of wack, "how much" wack are we talking here?

Yep, definetly floating point troubles.

Print "100000.0 + 0.1 ="+(100000.0+0.1)

WaitKey()

As you see, the number isn't added because of the rounding involved with floating point numbers. Best thing to do is to scale your world down a bit.

Good Idea. Scaling I shall do.
