How do I set sprite position right?

Hi. Sorry for my English.

I have one sprite "Player", and want to move this sprite only horizontal with mouse (arkanoid style).

System - Every tick - Player - Set X to Mouse.X

Its work, but in preview "Player" allways start in left coner of the layout. But I want set Player potition to the middle on start of layout. What I can do?

You can set

- X to LayoutWidth/2

- Y to LayoutHeight/2

BUT with everytick, it will set your player X as Mouse.X.

You will need a variable to trigger it.

Like:

State 0:

- X to LayoutWidth/2

- Y to LayoutHeight/2

On Mouse Click: set State to 1

State 1:

- X to Mouse.X

Now I set paddle vertical, and add this: clamp(Mouse.Y, WallTop.Y+Player.Height/2, WallDown.Y-Player.Height/2)

I can control paddle (player) vertical, but on start of layout, paddle appears on up side of layout. What else can I do to start the game with paddle centre of Y coordinate?

And another question. When I set mouse to control player (up and down), keyboard control ( 8 direction) stop working. How I do to work mouse movement a keyboard at the same time?
