Hi, is there any way to pass a variable for the property to be transitioned?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | local myRectangle = display.newRect(0, 0, 150, 50) myRectangle.strokeWidth = 3 myRectangle:setFillColor(140, 140, 140) myRectangle:setStrokeColor(180, 180, 180) --does not work --[[ local transitionProperty = alpha transition.to( myRectangle , {time=400, transitionProperty = 0 , transition=easing.outExpo }) --]] --does not work --[[ transitionProperty = "alpha" transition.to( myRectangle , {time=400, transitionProperty = 0 , transition=easing.outExpo }) --]] --does work, obviously :) transition.to( myRectangle , {time=400, alpha= 0 , transition=easing.outExpo }) |
Yes, although I can't work out what you are doing exactly above.
As an example, if you had a variable for transTime = 1000 you could pass it by doing this;
transition.to(myRectangle{time = transTime, x = 100, y = 100})
Make sense?
Thanks for using Lua tags to post your code; when people don't it's a real pain ;)
Hi Peach, thanks for your reply, however I'm not trying to pass a value for a property
ie
1 2 3 | local myval = 100 transition.to(myRectangle{time = 100, x= myval}) |
I figured it out!
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | local myRectangle = display.newRect(0, 0, 150, 50) myRectangle.strokeWidth = 3 myRectangle:setFillColor(140, 140, 140) myRectangle:setStrokeColor(180, 180, 180 local transData= {} transData.time=400 transData.transition=easing.outExpo if(somecondition~=true) then transData.x=0 else transData.y=0 end transition.to( myRectangle , transData) |
D'oh! Sorry, I completely misunderstood.
.... I really should stop forum lurking when I'm not all caffeinated ;)
