I hate double posting but people don't seem to see my first one... sigh. Anyway, I just want this piece of code:
Code:

if pointer_x >= 0 and pointer_x <= 98 and pointer_y >= 245 and pointer_y <= 272 and pad:cross() then
screen:blit(0,245,startpushed)
end

For it to stay blitted instead of letting go and it dissappear.. i want it to appear until i tell it to stop! Is there anyway to fix that??

Well, my knowledge of Lua is pretty skimpy, but usually what you need to do in a situation like this is to create a "flag" variable that indicates whether the image should be displayed, and then set or reset that flag based on the appropriate events. You didn't specify the circumstances under which the image should go away, but (for example) you could have it stay until you press the square by doing something like:

Code:

if pointer_x >= 0 and pointer_x <= 98 and pointer_y >= 245 and pointer_y <= 272 and pad:cross() then
showImage = 1
end

if pad:square() then
showImage = 0
end

if showImage > 0 then
screen:blit(0,245,startpushed)
end


This is untested code, but should give you some idea of how to proceed. Hope this helps!

if showblit == true then do
if pointer_x >= 0 and pointer_x <= 98 and pointer_y >= 245 and pointer_y <= 272 and pad:cross() then
screen:blit(0,245,startpushed)
end
end


showblit = true (will show blit)
showblit = false (will not show blit)
