leejohnson

cool, ill have to crack (i wana get this sorted before xmas) then i can spend a few days in front of computer. How would you add that to multi screen like my screen 3 and screen 32? or are you saying create a main screen and then lay over the mainscreen? i have uploaded i recent verison of my code t...

leejohnson

yes excalty what im after list of buttons in each screen, similar to how the icon and screen blit for each icon is. how would you write it out, code below is main screen two icons and two icon positions def Screen3(): # Main Screen screen.fill(white) override = pygame.image.load("icons/override.png"...

leejohnson

yes there is, i have cut out alot of the code as i thought it might be easier for you guys to link just 2 screens on 1 or two buttons rather than the rest. it is quite a big piece.

so is my understanding of a button inncorect then? or would people prefer me to post my working code to date?

leejohnson

Hey guys just to make sure i understand there are three sections to a button. 1. You define what a button is using the same script ive seen on a couple using x and y pos. this goes in the top part where you describe what things are? 2. In each def screen() the button is layout and told where the act...

leejohnson

before i added the button function to the script both screens worked and layout well in the 320 x 240 on a white back ground with my icons on there just had to change the screen mode == to what ever one. but when i add the button function i get loads of syntax errors, even Dirks version did not work...
