Yes, I have used the search, which gave huge lines of code that only generated Syntax Errors, and people that said they already knew how to make the object follow the mouse, and asked for something else. I looked through TDK's tutorials AND other tutorials and I couldn't find anything.
Can someone give me a code that creates a 2D circle and makes it follow the mouse?

Aren't I full of questions?

It depends on exactly what you mean. Programming is precise. Your request isn't.

What background is the circle moving over? Do you need to replace the background?

How should the circle follow the mouse?



That follows the mouse, but you are probably not wanting that.

So, please tell us exactly what you want in a bit more detail - we can't read your mind!

That is what I want, when I try that, the circle still doesn't follow the mouse.

Strange - what does it do for you?

It puts the circle at the position of the mouse... then stays there even if I move the mouse.

i think he wants the circle to lag behind the cursor

sinani, store the circle's current X position and Y position in variables. each loop, check whether the X position is less than or lower than mouseX(). increase it by a little bit if it's lower, decrease it if it's higher. do the same for the Y position and mouseY()

Lag? Cursor? First of all, the circle should be moving at the same speed of the mouse. Second of all, I should clarify that I am using the HIDE MOUSE command.
Ruccus, your code made a circle, made it stay at the corner of the screen, and then made it disappear.

Works fine for me. Are you talking about the actual code, or an attempt to implement my code into your own? Those are 2 very different things, and my code should work perfectly, unless your sync rate is at like 1.

If you want the circle to just be positioned at the mouse's position at all times... why dont you just draw a circle at the mouse's coordinates :S.

If you want it to follow the mouse with a delay, do what I did above.

Thats all there is to it...

Hmmm - that sounds very strange.

Might possibly be a Sync problem, but as Ruccus says, any snippet we give you that works on it's own can be rendered useless when you paste it into your own programs - for a multitude of reasons.

So first of all, let's find out if it's a problem with DB or your computer.

Copy the code snippet I posted into an empty DB project and just run it. Does it do what you want it to then?

If it does, then there's something in your code which isn't quite right. In which case, you would be better posting the section of code from your program where the snippet does not work.

You don't need to post the whole program - just create a small example from your program which doesn't work. There's a very good chance that doing that, you will probably discover why it's not working yourself.

TDK, your code works perfect for me. No lag with it just alone, and I even adjusted my mouse settings, just to see if I could break it.

Like you suggested, there must be some tie-ups (inner-loops) in his code slowing down the main loop.

Here is a working sample (DBClassic) . Showing the center of the circle (mouse position on left top) and the mouse is hidden.

He can't be that bothered about it - he hasn't come back in nearly a week!

I suspect the thread about net games will go much the same way...

Oh, hi guys.
I found my own way with the circle following the mouse. same goes with the thread about net games.

Did someone say 3D scanning on my desk, or was that just an AdBot?
