Smooth scrolling / panning

  • #1, by AkcayKaraazmakSaturday, 06. September 2014, 08:36 6 years ago
    When the character starts moving to edge of the scene, scenes are panning/scrolling. But how we could do that sliding smoothly. Camera start up with a speed and then slow down towards the end?

    It might be possible via LUA but I am not sure. Would love to see an option for that!!! Signed!!

    Yea mate, an option would be great! Lee told me that there are some tween parameters but they could only be accessed via LUA as you wrote.

    You can try my test script, I'm not completely happy with the result, but it's enough for some games:
    c_res=game:getPoint(VGameWindowResolution)
    sc_current={x=0,y=0}
    sc_cur=0
    function dist(x,y)
    return math.sqrt(math.pow(x.x-y.x,2)+math.pow(x.y-y.y,2))
    end
    function center_char()
    local c_position=game:getLink(VGameCurrentCharacter):getPoint(VCharacterPosition)
    local c_scroll=game:getPoint(VGameScrollPosition)
    local scene_changed=sc_cur~=game:getLink(VGameCurrentScene):getId().id
    c_position.x=c_position.x
    c_position.y=c_position.y
    c_position.x=c_position.x-(c_res.x/2)
    c_position.y=c_position.y-(c_res.y/1.5)
    c_position.x = math.max(0,c_position.x)
    c_position.y = math.max(0,c_position.y)
    if dist(c_position,sc_current)>300 or scene_changed then
    sc_current=c_position
    local delay=3000
    if(scene_changed)then
    delay=0
    end
    startObjectTween(game, VGameScrollPosition, c_scroll, c_position, delay, easeQuadInOut)
    sc_cur=game:getLink(VGameCurrentScene):getId().id
    end
    end
    registerEventHandler("mainLoop", "center_char")

    Go to scripts, create a script (you can name it what you want), paste it, the script should be marked as definition script, what's the default case.

    I played around with the "delay" and the "if dist"... somehow it work and it looks a lot smoother but sometimes it just won't scroll even though my character is leaving the screen border and there is still a little part of the background off screen.

    @SDMono: it's just a test script, needs a lot of tweaking for every game. Problem is, when distance is too high it won't scroll to some parts at the edge, too low and it will restart the scrolling to often, I tried it with the big scene in Whispered World, that worked nicely with these values. But I can't use magnetism to the edge of the scene because we can't get size of the background image yet...

    Would there be a way of changing the scrollspeed via LUA "game:setValue(VGameScrollSpeed, 200)" and increase it while the scrolling is going on?
