Hi,
I am stuck at a point when user is drawing line within letter shape.(ex: A) I want to check condition and don’t allow to user to draw line outside of shape A. And I also want to check that user has completely drawn or not. Is it possible? If anyone have any idea let me know asap.
Any help will be appreciated.
Thanks.

This is really, really rough but you could use something like this with multiple shapes that should work;
[lua]local obj1 = display.newRect( 100, 100, 20, 100 )
obj1.rotation = 45
local dot = {}
local function test (event)
t = event.target
bounds = t.contentBounds
if event.x > bounds.xMin and event.x < bounds.xMax and event.y > bounds.yMin and event.y < bounds.yMax then
dot[#dot+1] = display.newCircle(event.x, event.y, 10)
dot[#dot]:setFillColor(255,0,0)
end
end
obj1:addEventListener(“touch”, test)[/lua]
Let me know how that goes for you

Thanks for reply Peach
But this is not my case because I’m working on Arabic letter and that is having different shapes.
I want user to draw line under the shape border only.
I am going to use another way and need your help.
can we detect event when I’m moving a object over other object? If this is possible then
i can do my job.

Q: Can you detect when moving an object over another object?
A: Yes. There are multiple ways of doing this. You could have a touch listener on the object that is “underneath” and a flag, or you could use conentBounds and a flag.

Hi Peach,
I have already assign touch listener on the object that is “underneath”. but when object is moving over
underneath object then event is not detecting. I heve not idea conentBounds.
For more information I showing my code below.
[lua] onColission=function(event)
print(event.target.name)
eraseLine()
initializeCirclePos()
end
newLine = function ( event )
local body = event.target
local phase = event.phase
local stage = display.getCurrentStage()
if “began” == phase then
stage:setFocus( body, event.id )
body.isFocus = true
---------writing line----------------
if(tempLine==nil) then
isLine = true
tempLine=display.newLine(event.x, event.y, event.x, event.y)
tempLine:setColor(rcolor, gcolor, bcolor)
tempLine.width=selectedWidth
prevX = event.x
prevY = event.y
end
elseif body.isFocus then
if “moved” == phase then
if body.x > display.contentWidth then
body.x = display.contentWidth - body.width
body.y = display.contentHeight - body.height
elseif body.x < 0 then
body.x = body.width
body.y=body.height
else
body.x = event.x
body.y=event.y
end
if(tempLine==nil) then
isLine = true
tempLine=display.newLine(event.x, event.y, event.x, event.y)
tempLine:setColor(rcolor, gcolor, bcolor)
------tempLine.width=30
tempLine.width=selectedWidth
prevX = event.x
prevY = event.y
end
if isLine == true then
ractgangle_hit[lineIndex] = display.newLine(prevX, prevY, event.x, event.y)
ractgangle_hit[lineIndex]:setColor(rcolor, gcolor, bcolor)
-------ractgangle_hit[lineIndex].width = 30
ractgangle_hit[lineIndex].width = selectedWidth
local i
rc[rcIndex] = display.newCircle(ractgangle_hit[lineIndex].x,ractgangle_hit[lineIndex].y,selectedWidth/2)
rc[rcIndex]:setFillColor(rcolor, gcolor, bcolor);
writeScreen:insert(rc[rcIndex])
rcIndex = rcIndex + 1
ractgangle_hit[lineIndex].objname = “Point”…lineIndex
writeScreen:insert(ractgangle_hit[lineIndex])
–print("No of lines "…lineIndex)
prevX = event.x
prevY = event.y
lineIndex = lineIndex + 1
currLineIndex = currLineIndex + 1
end
elseif “ended” == phase or “cancelled” == phase then
stage:setFocus( body, nil )
body.isFocus = false

circle:toFront()

I believe setting the focus may be part of the issue, although I can’t read through this thoroughly tonight (time constraints) - if you post plug and play that would be helpful. [import]uid: 52491 topic_id: 27957 reply_id: 113309[/import]
Thanks Peach,
I got it.
The issue was with focus. [import]uid: 75428 topic_id: 27957 reply_id: 113327[/import]
Glad to hear it, good luck with your project!
