System Version: 10.5.8
HW Info (your computer specs): 2 GHz Intel Core Duo 4GB Memory
iPhone/iPod generation: iPod Touch 2nd Gen
iPhone/iPod firmware version: 3.1.2

Severity - 1 Showstopper(crash), 2 Critical(hang or failure), 3 Important(doesn’t function as planned),
4 (annoying/aesthetic), 5 (N/A): 3

Reproducibility (Every time, intermittent, only happened once, n/a): Every Time

Description:The order in which Text Object properties get updated produce different results

Steps to reproduce (keep this as simple as possible):

  1. Run the below code. The text slides across screen (NOTE the order in which the Text object properties are updated):
local txt = display.newText( "", 0, 0, nil, 10 )  
txt:setTextColor( 255,255,255 )  
  
local function onEnterFrame( event )  
 txt.x = txt.x + 1  
 txt.y = txt.y + 1  
 txt.text = event.time -- this is done last: prior updates have effect  
end  
Runtime:addEventListener( "enterFrame", onEnterFrame )
  1. Run the below code. The text DOES NOT slide across screen (NOTE the order in which the Text object properties are updated):

[code]
local txt = display.newText( “”, 0, 0, nil, 10 )
txt:setTextColor( 255,255,255 )

local function onEnterFrame( event )
txt.text = event.time – this is done first: subsequent updates ignored
txt.x = txt.x + 1
txt.y = txt.y + 1
end
Runtime:addEventListener( “enterFrame”, onEnterFrame )

Related to the above:

The below code keeps the displayed text at the top-left corner of the screen, even as the texts’ length increases:

local txt = display.newText( "", 0, 0, nil, 10 )  
txt:setTextColor( 255,255,255 )  
  
local function onEnterFrame( event )  
 txt:setReferencePoint( display.TopLeftReferencePoint )  
 txt.x = 0  
 txt.y = 0  
 txt.text = event.time  
end  
Runtime:addEventListener( "enterFrame", onEnterFrame )

The below code seems like it should do the same as the above code, but it does not (The text is centered about 0,0 or very close to it, as if the lines marked A,B and C are being ignored):

local txt = display.newText( "", 0, 0, nil, 10 )  
txt:setTextColor( 255,255,255 )  
txt:setReferencePoint( display.TopLeftReferencePoint ) -- A  
txt.x = 0 -- B  
txt.y = 0 -- C  
  
local function onEnterFrame( event )  
 txt.text = event.time  
end  
Runtime:addEventListener( "enterFrame", onEnterFrame )
