Smooth scrolling / panning

This thread is a few years old. Some details may refer to an earlier version of Visionaire Studio. Current tutorials

    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")

    Thats cool mate, thank you so much!. I'll give a try on it. But how I gonna execute it? In what action, should I write it of execute script? I'm a very beginner level in Vs.

    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.

    Thanks SimonS... gonna try it out and get back to you! smile

    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.

    I was looking for this kind of script, thanks a lot SimonS ! wink

    @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?
