Hey there i was trying to do a game for an isu in school, but so far its crap. Its supposed to look like this game http://www.addictinggames.com/worm.html
but it doesnt work properly. I would add the code i have so far but i left it at school. It'd be great if you could help me out. Thanks

code:

View.Set("offscreenonly")
var mx, my, b : int
var x, y : int
x := round(maxx/2)
y:=maxy
loop
    Mouse.Where (mx, my, b)
    if b = 1 then
        y += 5
    else
        y -= 5
    end if
    cls
    Draw.FillOval (x, y, 5, 5, red)
    View.Update
    if y < 0 then
        y := 0
    end if
    if y > maxy then
        y := maxy
    end if
end loop

making gravity is not difficult.
you have an x and y position of your worm. you also have a vx and vy values for your worm. these values are the x and y velocities of the worm. to make gravity, just make the dy value decrease by a certain amount each time the loop executes.

EXAMPLE CODE
code:

setscreen ("offscreenonly")
var x, y : real
var vx, vy : real
x := 0
y := 100
vx := 1
vy := 3

loop

    x += vx
    y += vy

    vy -= 0.015

    exit when y < -10

    cls
    drawfilloval (round (x), round (y), 5, 5, black)
    View.Update

    delay (10)

end loop

jeeze tony, add a delay Confused
anywho, to add gravity to tony's code...

code:

setscreen ("offscreenonly")
var x, y : real
var vx, vy : real
x := 100
y := 100
vx := 0
vy := 3
var mx, my, mb : int
const gravity := 0.02

loop

    Mouse.Where (mx, my, mb)

    x += vx
    y += vy
    vy -= gravity
    if mb = 1 then
        vy += 0.2
    end if

    cls
    drawfilloval (round (x), round (y), 5, 5, black)
    View.Update

    delay (10)
    exit when y < -10

end loop

Ya i pretty much get the gravity part of it, but the only thing i need is to like get the game to scroll past or sumthing like that ... and i aslo need bricks to move with the worm

thanks with the help so far though

well you need to randomly generate a maze that the player tries to get through. Bunch of ways to do that im sure. Then, once you've done that, every time through the loop move each object in the maze to the left (or right, but its left in the worms game on addictinggames.com). then check for a collision. shouldn't be that difficult.

hey, can somebody explain to me what it means when you do x += y

what the heck is += ?

By the way, nice gravity.

It's just short for x = x+y

ex:
x += 1 is x = x+1
x -= 1 is x = x-1

and there you have it. I'm probably wrong though.
