This is a very simple question (I think/hope)

I want the rotation of this box to be controlled by the mouse - when the left mouse button is held down the box moves forward. Simple.

I have succeeded in doing such a thing - BUT - if you move the mouse cursor to the far left/right side of the screen the box will stop rotating because mousex() can't get any higher/lower.

Is there any way to allow the box to continue to rotate? Perhaps by centering the mouse cursor again?

Have you tried something like this?


[edit] I didn't read it correctly the first time Red_Eye's is what you need I think. Re-edited my code to make the box rotate even if the mousebutton is not clicked.

Thanks for the help but it didn't work I open DBP and whacked your source code in and ran it. But the block didn't rotate with mousex().

I guess I couldn't have made it clear what my problem was...

I have a box which rotate with mousex() and moves forward with mouseclick. However if the mouse cursor hits the side of the screen (I'll use the left side as an example) the mousex() value can no continue to get lower as it is already equal to 0 and cannot move past the edge of the screen and so the box cannot rotate any further in that direction.

That wrapvalue function looks interesting - could you perhaps explain it?

Look at my snippet above. I edited it. ReD_eYe's only rotates the cube when you click the mouse button.

[edit]
Quote: "WRAPVALUE
This command will return a value that does not exceed the range of 0 to 360. Where a value is specified that exceeds this range, the command will wrap the value around to bring it back within the range. This command is best understood by using the number of a clock as a mental picture of how a number wraps. If the clock hand points to 11 and is then advanced 2 hours, the number has to wrap from 12 around to 1 to keep the cycle going. The parameter should be specified using a real number.

SYNTAX
Return Float=WRAPVALUE(Angle Value)
"


From the help files. Good luck.
