I can help you with the mouse click events.
The function is dbMouseClick() which returns an int depending on which mouse button was clicked (1=left click, 2=right click, 4=middle button and 8=fourth button click if any, and their sums if they're clicked together for example 3=left and right), so you would need in your game loop for, say, left click:

2. You should check the mouse position. I have made a function that checks if the mouse is over a sprite:


3. The stretch value is in percent. You must count how many percent the image should stretch to fit the screen. And you can't stretch images for some reason, you must use sprites. Here is an example of a stretching function:

Thanks CheatCat,

dbMouseX()
dbMouseY()

There is no mention in the "Dark GDK" -> "Documentation" -> "Information" , of the existence of there 2 functions.

I always wondered how people found the actual mouse position.

If the following doesn't do it then I don't know what the problem is.

There is nothing wrong with your particular function.
It compiles fine by itself.

The problem lies somewhere else in your code ..... maybe your function prototype is faulty, or you are calling it incorrectly within your code, or there is another coding error that is making the compiler think your function is faulty.

Looking at the error again it might be that the function is defined in the wrong place. The compiler complains that local functions are illegal. Local to what? Inside another function maybe?

Let us look at your "if" conditions.

Your first one:

if ( dbMouseX()> 0 && dbMouseX()< 0 + 200 && dbMouseY() > 0 && dbMouseY()< 0 + 70 )


I always use brackets to make sure there is never a chance of confusion, or possibility of errors. I would have written it as:

if ( (dbMouseX()> 0) && (dbMouseX()< (0 + 200)) && (dbMouseY() > 0) && (dbMouseY()< (0 + 70)) )

I suspect the way you have written your line, it actually equates out to:

if ( 70 )

Maybe some one else can confirm this as I could be wrong.

You may not be checking for the condition that you think you are checking for.

You're right, the tests need to be nested properly.

One other thing to keep in mind is that the dbMouseClick(int button) function will register a true as long as the button is held down. You have to manage it in order know know when the mouse button is newly clicked or released. Otherwise you can end up with a click status inside a loop as long as you hold down the button. Regardless of how quickly you may click it, it can still register as multiple clicks.
