how to cancel a transition

Getting Started Newbie Questions
#21

I got it! I got it!!! YES!!!

Where you put the – transition.cancel(greenBar1Tween) – inside the doneButton.

I kept thinking,

"If here you cancel the transition, just make the green bar equal to the starting point.

and then make it invisible."

So I try in different ways – invisible first , the .x = 150 (it didn’t work)

I put it in a different way and it works!!!

local function doneButton ()         transition.to(done, {time=200, y=(centerY + 600)})         transition.to(song1, {time=100, x=opX, y=opY, xScale=1, yScale=1})         audio.stop ()         transition.cancel(greenBar1Tween)         greenBar1.x = 150         greenBar1.isVisible = false     end

Now when I stop the green bar, any time…

and I start the music again, the little green bar starts from the beginning…GREAT!!!

thanks for all your help.

I’m really proud of my self, I’m learning, I’m learning…

Programming is all about “what and how to do thinks? - code it later” :stuck_out_tongue: First you must state your problem. Think how you would do it, what you need and then write code :slight_smile:

I thought I got…sad…

something very strange is happening.

I have 2 green bars – one on top, one on the bottom.

----------THIS IS THE FIRST TIME I RUN THE CODE-----------

When I run the code the first time

the TOP green bar moves from x=1 to x=100

at the end

the BOTTOM green bar moves from x=1 to =100

if I cancel the transition on the BOTTOM first…

everything works fine, perfect.

I can reset the music and start all over and no problem

I can do it as many times as I want.

The problem is if I stop the transition on the TOP green bar.

I get a nil value – File: ? in line 75

here is where I have the cancel the BOTTOM green line

I don;t get it.

I changed – greenBar1Tween – for || reset1 || and || reset2 ||

local function doneButton ()         transition.to(done, {time=200, y=(centerY + 600)})         transition.to(song1, {time=100, x=opX, y=opY, xScale=1, yScale=1})         audio.stop ()         transition.cancel(reset1)         greenBar1.x = 150         greenBar1.isVisible = false         transition.cancel(reset2)         greenBar2.x = 150         greenBar2.isVisible = false     end

What is happening?

if not one thing, — it’s another …

you need to have a lot of patience for programming… a lot.

I admired you guys a lot.

I thought I might use an “if – else” statement. There I go.

local function doneButton () &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; transition.to(done, {time=200, y=(centerY + 600)}) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; transition.to(song1, {time=100, x=opX, y=opY, xScale=1, yScale=1}) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; audio.stop () &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if greenBar1.x \< 1000 then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print ("this is the FIRST time") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.cancel(reset1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;greenBar1.x = 150 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;greenBar1.isVisible = false &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; elseif greenBar2.x \< 1000 then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print ("this is the SECOND time") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;greenBar2.isVisible = false &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.cancel(reset2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;greenBar2.x = 150 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end &nbsp;&nbsp;&nbsp; end

I try different forms, I think I have the idea…

I even put “print”

but in Terminal I don’t see the SECOND time

I guess it’s not detecting the – elseif ********* then

I don’t know why.

I really need help, I’m very close, but not yet!

sorry I did not see the “Full code please”

here it is.
