Glitch in the matrix!! Fixed :]

Hello fellow game makers..

So far I have code that when you click and drag an image it replaces it with another image. Everything seems to work great until I move the object over another object.. That object gets removed. :(

Here is the code:

--[[
        PROJECT OBJECTIVES
        
        OBJECTIVE 1:
        
        Pick weeds and make them appear to be uprooted.
        
        OBJECTIVE 2:
        
        Spreed good seeds to grow
        
        OBJECTIVE 3:
        
        Water plants and watch them grow
        
        ]]
 
 
display.setStatusBar( display.HiddenStatusBar ) -- HIDE STATUS BAR
local loqsprite = require('loq_sprite')
math.randomseed(os.time())
math.random()
 
local _W = display.contentWidth
local _H = display.contentHeight
 
local weedTable = {}
local unrootTable = {}
 
local t1 = {
        
        { x = 650, y = 365 },
        { x = 350, y = 380 },   
        { x = 550, y = 480 },
        { x = 400, y = 550 },
        { x = 700, y = 600 },
        
}
 
local background = display.newImageRect("background.png", 1024, 768)
background.x = _W/2;  background.y = _H/2 
 
for i=1, 5 do
        local unrootWeed = display.newImageRect("picked.png", 236, 221)
                  unrootTable[i] = unrootWeed
                --unrootTable[i]:setFillColor(255,255,0)
                  unrootTable[i].isVisible = false
end
 
local function drag_unroot(event)
        if event.phase == "moved" then
                event.target.x = event.x
                event.target.y = event.y
        end
end
 
local function drag_weed(event)
                local id = event.target.id
        if event.phase == "moved" then
           print(id)
           event.target.x = event.x
           event.target.y = event.y
           event.target:removeSelf()
           event.target = nil
                   weedTable[id].isVisible = false
           unrootTable[id].isVisible = true
           unrootTable[id].x = event.x
           unrootTable[id].y = event.y
           unrootTable[id]:addEventListener("touch", drag_unroot)
        end
        return true
end
 
for i=1,5 do
        local weed = display.newImageRect("weed.png", 200, 150 )
                weedTable[i] = weed
            weedTable[i].id = i
                weedTable[i].x = t1[i].x;
                weedTable[i].y = t1[i].y;
                weedTable[i]:addEventListener("touch", drag_weed)
                print(weedTable[i].id)
end

+1, its all because of the event.target thing in drag_unroot function
it may be cured by disallowing event to propagate except object in question

anyone know how to do this? any help is appreciated

try setting focus

I am new to setting the focus.. do you do something like this?

event.target.isFocus = true

heres a snippet from one of my files

 if event.phase == "began" then
            display.getCurrentStage():setFocus( event.target )
            event.target.isFocus = true
        elseif event.phase == "moved" then
            event.target.y = math.min( 380, math.max( 140, event.y) )
        elseif event.phase == "ended" or event.phase == "cancelled" then
            display.getCurrentStage():setFocus( nil )
            event.target.isFocus = false
            ctrl[1] = math.floor( ( ( 380 - control[1].y ) / 24 ) + 0.5 )
            ctrl[2] = math.floor( ( ( 380 - control[2].y ) / 24 ) + 0.5 )
            print( ctrl[1]..","..ctrl[2] )
            fnSetControl()

if it helps someone, heres the finally working code:

local oneTable = {}
 
 
local function foo(event)
if event.phase == "began" then
display.getCurrentStage():setFocus( event.target )
            event.target.isFocus = true
        event.target.text = "unroot"
        print(event.target.id)
elseif event.phase == "moved" then
                event.target.x = event.x
                event.target.y = event.y
elseif event.phase == "ended" then
        display.getCurrentStage():setFocus( nil )
            event.target.isFocus = false
end
end
 
for i=1, 5 do
 
local root = display.newText("root",0,0,nil,30)
root.id = "#: "..i
oneTable[root.id] = root
root.x = math.random(50,500)
root.y = math.random(50,500)
oneTable[root.id]:addEventListener("touch", foo)
end
 
for i,v in pairs(oneTable) do
print(i,v)
end

NIIIICE!!

how do I get that other picture back though?

I tried this but the other word keeps on following the mouse..

local weedTable = {}
 
 
local function drag_weed(event)
if event.phase == "began" then
display.getCurrentStage():setFocus( event.target )
            event.target.isFocus = true
        unroot = display.newImageRect("picked.png", 236, 221)
                        unroot.x = event.x
                unroot.y = event.y
           unroot = event.target
        print(event.target.id)
elseif event.phase == "moved" then
                event.target.x = event.x
                event.target.y = event.y
elseif event.phase == "ended" then
        display.getCurrentStage():setFocus( nil )
            event.target.isFocus = false
end
end
 
for i=1, 5 do
 
local root = display.newText("root",0,0,nil,30)
root.id = "#: "..i
weedTable[root.id] = root
root.x = math.random(50,500)
root.y = math.random(50,500)
weedTable[root.id]:addEventListener("touch", drag_weed)
end
 
for i,v in pairs(weedTable) do
print(i,v)
end

This code seems to server my purpose in this app so it is now 100% complete

Here if anybody wants to take a look..

local _W = display.contentWidth
local _H = display.contentHeight
 
local weedTable = {}
 
local unroot
 
local background = display.newImageRect("background.png", 1024, 768)
background.x = _W/2;  background.y = _H/2 
 
local t1 = {
        
        { x = 650, y = 365 },
        { x = 350, y = 380 },   
        { x = 550, y = 480 },
        { x = 400, y = 550 },
        { x = 700, y = 600 },
        
}
 
local function drag_unroot(event)
        if event.phase == "moved" then
                        display.getCurrentStage():setFocus( event.target )
                unroot.x = event.x
                unroot.y = event.y
                                 unroot.isFocus = true     
      
                      end
        end
        
 
local function drag_weed(event)
        if event.phase == "began" then
                print(event.target.id)
                event.target:removeSelf()
                event.target = nil
                unroot = display.newImageRect("picked.png", 236, 221)
                --unroot:setFillColor(255,0,0)
                unroot.x = event.x
                unroot.y = event.y
                --event.target.isFocus 
                unroot:addEventListener("touch", drag_unroot)
        if event.phase == "end" then 
                 display.getCurrentStage():setFocus( nil )
                 unroot.isFocus = false     
        end
              end
        return true
end
 
for i=1,5 do
local weed = display.newImageRect("weed.png", 200, 150 )
weedTable[i] = weed
weedTable[i].id = "weed #: "..i
weedTable[i]:setFillColor(0,255,0)
weedTable[i].x = t1[i].x;
weedTable[i].y = t1[i].y;
weedTable[i]:addEventListener("touch", drag_weed)
end
 
 
for i,v in pairs(weedTable) do
print(weedTable[i].id)
end
