how to drag -> scroll

Hi,

Please I like to know if somebody has tried to change the drag move of a RPG map to a scroll move, or know how to do that?

Thanks

Do you mean to drag the map around by touch? If so, try this:

local onTouch = function( event )
     map:drag( event )
end
 
Runtime:addEventListener( "touch", onTouch )

Hi Grahan,

Thanks the quick answer, but what I want is to change this "map:drag(event) " movement, by using the scrollView.lua library of Corona, which have the " stopping delayed" effect.

you must try to change the part of the code responsible for moving the map, so instead of following your finger, it moves in a direction relative to the starting point (when you clicked)

I tried to put a lime map in the scrollView sample

display.setStatusBar( display.HiddenStatusBar ) 
 
--import the scrolling classes
local scrollView = require("scrollView")
 
-- Setup a scrollable content group
local topBoundary = display.screenOriginY
local bottomBoundary = display.screenOriginY
local scrollView = scrollView.new{ top=topBoundary, bottom=bottomBoundary }
 
system.activate( "multitouch" )
local lime = require("lime")
 
local map = lime.loadMap("tutorial16.tmx")
 
local player = nil
 
local onPlayerCreate = function(property, type, object)
        player = object
end
 
map:addPropertyListener("IsPlayer", onPlayerCreate)
 
lime.createVisual(map)
lime.buildPhysical(map)
scrollView:insert(map)
 
-- Important! Add a background to the scroll view for a proper hit area
local scrollBackground = display.newRect(0, 0, display.contentWidth, scrollView.height+64)
scrollBackground:setFillColor(255, 255, 255)
scrollView:insert(1, scrollBackground)
 
scrollView:addScrollBar()
 
map:setFocus(player.sprite)
 
local onUpdate = function(event)
        map:update(event)
end
Runtime:addEventListener("enterFrame", onUpdate)

I'm replying on my phone so sorry for the short reply, try inserting map.world rather than just map.

Hey Graham, is working now, let me try to insert the map I wanna.
Thanks again, this is a great support to your costumer, see you in the next doubt.

No worries, very happy to help.
