Creating a working rollover image.

Hello all, I have been browsing around the forums and I am very impressed, although I am not quite upto your level in the Lua programming, I am striving to get better. Anyways heres what I need some help with.

I have a start menu for my game with the options: Play Now, Settings, Credits.

I am using this code to display my pictures:

Code: Select all

   screen&#58;blit&#40;0, 0, background, 0, 0, background&#58;width&#40;&#41;, background&#58;height&#40;&#41;, false&#41;
   screen&#58;blit&#40;300,75, menu1img&#41; 
   screen&#58;blit&#40;300,125, menu2img&#41; 
   screen&#58;blit&#40;300,175, menu3img&#41;

What I would like to learn is how to make use of the d-pad with the UP and DOWN arrows to select these images and call another image to act as a rollover image...

That is it for now, any help or reference to something like this would be very much appriciated. Thank you for your time.

I do this in Lowser. It's pretty simple: use a number variable as an index for the currently selected item. When down is pressed, increase the index, and opposite for up. In the blit section, blit the overlay image according to the index;

Code: Select all

screen&#58;blit&#40;300,75+50*menuIndex, menuOverlayimg&#41;

use a number variable as an index for the currently selected item.

How would I do that? Sorry if this is a stupid question, I will keep searching.
