Just discovered this. I have a character moving across the screen at
a very slow rate. His complete journey should be around 20 minutes,
making every frame increment at 0.0256527777777778. However, adding
this to _x isn't even registred, meaning adding 0.0256527777777778 to
0 (as _x) means _x will remain at 0. FOREVER.
Adding 0.0256527777777778 to a temp variable, and setting _x to that
variable rounded worked fine.
Any particular limitation of _x here that i wasnt aware of? Probably.
Yes. *Apparently* positions on the stage are based on twips, or 1/20th
of a pixel, so the least it can actually move is 0.05 pixels. The kind
of incrementation you're done - on movieclip properties - really
should be done on a separate temp variable, as most of the properties
seem to have similar precision limitations.
Well actually they MUST be done on a separate temp variable, because _x
won't even register the change. I expected it to increment the property
until it reached whatever threshold it required to make an actual visual
change, but adding less than 0.05 won't work, period. Anyway no big deal
:) I was just surprised i didn't know about it for so long.
