Mouse Buttons respons as pressed down?

[Alx101]

Hi, im having a problem with my code. Irrlicht seems to register that my mouse buttons it pressed down even though i don't press them. It is either that or my error checking is wrong.

The ouput i get is that it prints out "HI" even though i don't press the left mouse button. There is nothing wrong with my mouse. Any help?

You have two complete independent instances of Mouse which have nothing to do with each other (except having the same structure). One in EventH and one in main(). You can't expect that the one in main - which you are checking - is affected by changing a complete different place in memory (receiver.mouse). Think of classes/structs as stamps. Think of your memory as paper. Now each time you create a variable you push your struct-stamp somewhere on that paper. And if you now write some values in that part of paper obviously all other parts are not affected.

Also you should initialize all variables. Especially until you really, really know what you are doing initialize _every single variable_!. For structs you can do that in the constructor. Right now leftButton has a complete random value depending on whatever was in memory before you put your struct "ms" there.

[Alx101]

Oh ok. Didn't realize that. However i cant init the struct inside of the class since it gives me an error that should not be there :C.

[Alx101]

It works now. Thank you so much for your patience in the unskilled ones

[CuteAlien]

a) You can. For example in Your EvenH constructor you could write: "mouse.leftButton = false;"
b) Mouse can have it's own constructor - which is even better. So you can initialize all it's members there (as you usually should).

[Alx101]

But don't i do that in the struct Mouse?

[CuteAlien]

Unless I'm not seeing it you don't seem to initalize the values anywhere. There is no automatic initialization in c++ (neither in c).

[Alx101]

I think i do it in here

Code: Select all

struct Mouse
{
     bool leftMouse;
     bool rightMouse;
     core::vector3df Position;
}

[serengeor]

I think i do it in here

Code: Select all

struct Mouse
{
     bool leftMouse;
     bool rightMouse;
     core::vector3df Position;
}

Where?

There is no automatic initialization in c++ (neither in c).

Is the "leftMouse=false; rightMouse=false;" invisible or what?

[Alx101]

Oh got the initialization thing wrong. That is what i thought what you meant by initialization. The thing you meant i call to set the variable to a value.
