in a standalone eboot the "break" command simply restarts the lua application.

Ohhh ok. Then I have no idea. :(

it is actually a good thing to have in your code as u edit, so u dont have to reboot your game to test the changes, just press start. gets rid of the time it takes to display the gameboot.

actually "break" doesnt exit the program. it only exits the loop. so if u had two loops, it would transfer the control to the other loop.

okay, n00b question:

this is my code:

Code:

-- loaded images

health1 = 100
health2 = 100

hit1 = "false"
hit2 = "false"

-- added the bullet stuff

function collision()

for g = 1, 10 do
if (BulletInfo[g].x < Player[2].x + 32) and (BulletInfo[g].x > Player[2].x) and (BulletInfo[g].y < Player[2].y + 32) and (BulletInfo[g].y + 5 > Player[2].y) then
BulletInfo[g].firing = false
hit2 = "true"
end
end

for h = 1, 10 do
if (BulletInfo2[h].x < Player[1].x + 32) and (BulletInfo2[h].x > Player[1].x) and (BulletInfo2[h].y < Player[1].y + 32) and (BulletInfo2[h].y > Player[1].y) then
BulletInfo2[h].firing = false
hit1 = "true"
end
end

end


function health()

if health1 < 0 then
health1 = 0
end

if health2 < 0 then
health2 = 0
end

if (hit1 == "true") then
health1 = health1 - 10
hit1 = "false"
end

if (hit2 == "true") then
health2 = health2 - 10
hit2 = "false"
end

if health1 == 0 then
screen:clear()
screen:blit(0, 0, win2)
fire = false
end

if health2 == 0 then
screen:clear()
screen:blit(0, 0, win1)
fire = false
end

end


while true do

collision()
health()

screen.waitVblankStart()
screen.flip()
end

the problem is, even if one bullet hit the enemy, his health goes all the way down to 0 insted of just lowering by 10.

help.

How about in your function collision, instead of "hit2 = "true"" or "hit1 = "true"", just put, health1 = health1 - 10

You can exit from LuaPlayer using os.exit()

You have to use unofficial Luaplayer versions, such as v0.17dk2 by Dark Killer or v0.20 mod by Cools, both of which have a System.Quit() function (Cools got his from Dark Killer's) that "exits Lua Player back to the psp browser." I haven't tested this yet but I assume it works. I'm sure somebody here could confirm this.

I never saw the point of that function when you could just use os.exit()

Darnet! I wished I known that earlier. Too late now, I've already coded the program. It would be too much work to put that in. Guess I'll have to settle with the home button.

I wasn't referring to you. Yes, it does work. I use it in ID3PSP.

then the same thing happens.
