Scrolling

[Enigma666]

Hi,

What i want to make is a list, that can only draw out, for example 15 players.

If i scroll down, one less at top, and one new comes at the bottom, so basically just like how scoreboards work.

I know the required events and all that.

Ive been having this problem for a while and couldnt figure it out.

Thanks.

Add a variable called "offset" and increase/decrease with when you move the mouse wheel.

How does that help me at all?..

Use it in rendering as positioning.

If a player uses the "mouse_down" "key" you could make offset = offset - 10.

If a player uses the "mouse_up" key you could make offset = offset + 10.

You have to do some maths to do this, and you also have to calculate where it should stop, otherwise it would go out of the scoreboard or will show a blank scoreboard ^^

That is exactly what i need. The rendering part. [yep, failed at maths last year]

[Gallardo9944]

That's not even maths tho

Wel, i have no idea how to do it.

Anyone?

Anyone?

  
local offset = 0 -- offset should be 0 by default 
function scoreScroll(side) 
  if side == "mouse_wheel_down" then 
    offset = offset + 10 -- scroll down 
  elseif side == "mouse_wheel_up" then 
    offset = offset - 10 -- scroll up 
  end 
end 
bindKey("mouse_wheel_up","down",scoreScroll) 
bindKey("mouse_wheel_down","down",scoreScroll) 
  
--Later in your rendering part 
dxDrawText(text,px,py+offset,sx,sy,...) -- render, including scroll

Yes, im aware of the moving part, its just the rendering part, which im not really aware of. The basic idea is a list, on scroll one less shows at top, and one more shows up at bottom. I dont think that this offset way does that.

[Gallardo9944]

It does if you add more checks before actually drawing and moving.

Well i have basically no idea what you are talking about really.. lol
