World.Mouse function errors

Unhappy World.Mouse function errors - 05-06-2009, 09:27 PM

On both Mac and Linux, using the Mouse.getDistanceFrom(Top/Left)Edge function returns 'None' (And when I try to use it in an equation for my game, it crashes entirely). I tried, and 2.2 doesn't seem to work for this either. Is there a reason this, (Does it not just return a number?) or is it just a problem with the Mac and Linux versions of Alice?
Please help, and an early thanks to anybody who responds.

Huh, I'm still new to Alice and never used that function but I just tried it out and it worked for me on a windows, I can try on a linux later but I'll include the game file.


Just make sure to right click on my world variable called "x-value" and "y-value" then check watch this variable. Then run the game. This was actually a game file I was working on from another poster.




Tell me if it works for you.

I didn't actually see those variables in the version you posted, but taking the hint I added my own "x-value" (see attached) and the function works fine.

Not really a surprise as it has worked for me well in the past. Note that this is with Alice 2.0 - haven't tried it with other versions.

Default It crashes with an error message. - 05-07-2009, 07:51 PM

I tried that one, and Alice closed out of the player and gave the message:
Quote:
Alice has detected an error with your world:
what must not be null.
It highlighted the say method. I would have a picture of the whole error message, but I can't take screenshots while the message is present for some strange reason. I tried the function on a separate Windows laptop, though, and it did work.

Ok well to GregW question. Yes I tried the way you suggested and my program crashed also. But there are many other way of manipulating the variables with strings! For one I tried out "think" and it worked, you can assign it to 3D text also.

This may be a version thing - the program works fine for me with 2.0 - yet the error message would seem to indicate that the function didn't actually work for some reason. I really don't understand why the other methods work.

What versions of Alice are you using? And does the value of x-value actually change (look at the variable in the world properties window)/
