help with project

on the Balloon Tap game i didn’t want to use the balloon i wanted to use my own image but once its in the simulator my image has a white background so how do make it so that the image is there without the background. i want to add more platforms for my image to jump on and continue up the screen so how do i get more platforms and have the screen to move along with the balloon ? 

If you search the internet you can find various tutorials and samples of corona apps that use scrolling backgrounds.

Just doing a simple search just now, I found this one.  I have not watched it, but I am sure you can learn some of the scrolling stuff here, as well as other links

and this one, which may be more specific to your question ‘vertical scroller’. It’s title implies that. I have not read it.

If you search you are likely to find more.  I usually, when I am trying to learn something look a several examples.  One is more likely to explain itself better then another…  or the combination of the different tutorials sometimes helps the light bulb turn on!

As to the white around the balloon.  My guess is that might be a .jpg image.  They have backgrounds like that.  If you can get ‘gimp’ for mac or ‘paint’.net’ for PC  … open the image in the program and export it back out as a .png … you may have to first use one of the tolls int he program to clear the background, then export it as png.  Both those programs are free.

Various other devs on the forum here are likely to weigh in with more suggestions as well.

Hope this helps.

Is your image with the background a .PNG or .JPG file?

If your image needs to be .PNG so that it can have a transparent background
