Mouse movement sound off opportunity and work arounds

[rubes]

I've read many times Here that we shouldn't use the mouse movement, but I'm curious as to why this is. In pong games, for example, it can cause vertical movement, but isn't this rectified with an always set y to a value? The reason I'm intrigued by it is simplicity and quick response. If I were to code the arrow keys to move the paddle, I don't know how I would replicate the panic move equivalent of spinning the dial in pong to travel very fast to one side of the screen. On the flip side, is there a way to use mouse movent while causing the object being controlled to experience a slow down in response

When you use the mouse movement, mmf deactivates the mouse conditions in the event editor, and the the mouse acts like a joystick instead, where LMB = Firebutton 1 and RMB = Firebutton 2. Most people like to keep beeing able to use the mouse condition in the event editor, and therefore code their own mousemovement, which practically works exactly the same as the built-in mousemovent, only this way they are able to use the mouse conditions. You can easily code events to make an object behave exactly as it would if it had its movement set to Mouse-movement.

* Always
- Paddle: Set x-position to XMouse

This simple event is enough to make a horizontal mouse-movement.

If you don't want the paddle to go all the way to left or right, you can add events to restrict it's movement zone.

* X-position of Paddle < 32
- Paddle: Set X-position to 32

* X-position of Paddle > Frame width - 32
- Paddle: Set X-position to Frame width - 32


This is common practise, but it is of course up to you how you want to make your game
This method gives more control coding wise, and that's probably why most people prefer it.

OK, that makes sense. I'll add that now and see what happens. This might give me an idea on the slow down effect that i want too, but im not sure yet.....

For a fluid movement that won't leave the frame, you could probably do something like this. I haven't tried it, but if you have an object named Paddle with the hotspot horizontally centered it should work.

Always:
Set X Position of Paddle to max((X Right("Paddle")-X Left("Paddle"))/2,min(Frame Width+(X Left("Paddle")-X Right("Paddle"))/2,(9*X("Paddle")+xmouse)/10.0))
