Hi. I was working with images and stuff and I realized I needed a tool that told me where the X and Y was of the mouse. I then told myself that I should make it because it would be good practice.

Here is my code:


I made it so the mouse would dissapear and it would tell you the spot of the place you just clicked. But every time it tells me the position is 0 , 0 ,0 . What is the problem?

First, it should be:



That way, you will assign a value for the 3 variables.

Second, when you do that, Mousexposition - the z one, they will always be what you assigned them at the beginning.



That will do what you want, also, please indent your code.
If you do not know how, look at this.

No prob.

I would advise working through some of these tutorials:

Definitely TDK's, that is how I learned most of what I know. =P

So I don't even need the:

mousex() = this#
mousey() = that#

?

*

Also, you could use those, but just put them at the beginning of the loop, like:

Also, the mouse commands return an integer, so there is no need to assign a float variable to it. Use mousexposition instead of mousexposition# (same for y and z mouse coordinates).

does it matter? i guess, if you had like 10.000 variables and you increase fps perforamnce by 0.0001 by making a variable integer instead of float...

It is poor programming practice to use a float when an integer is required IMO, even though the speed difference is neglible. Why even have integers at all, if floats should be used for everything? If having clean code doesn't matter to you, then go ahead and do it up.

For small programs, it does not matter. But when programs get large, with hundreds to thousands of variables, that is one fast way to use up all the RAM in a machine.
