I Need Help Please!!!!

What is it you are trying to achieve?
<Replace all the <> with your answers/code and remove the <>>

I really need help creating a mini-game with basic things we just learned basic turing codes
of how to make a game, where you have a paddle, and balls fall down the screen
and when it hits the paddles, it bounces back, can someone please help me, or if you have
a previous code can you message it to me, i really need help

You need to answer these questions, we are not here to do the work for you, we are here to help you do it yourself.
If you have any specific questions, ask away, and we can help you get started.

this is rough code for a wall not a paddle i think you could customize for yourself

code:

View.Set ("graphics:1000;800,offscreenonly") var x, y : int % coordiantes for ball var px,py,px1,py1:int % coordinates for paddle x := 300 y := 200 px := 550 py := 100 px1 := 600 py1 := 300 loop cls() x := x + 1 if x > 550 then x := x - 1 end if Draw.FillOval(x, y, 10, 10, black) Draw.FillBox(px, py, px1, py1, black) View.Update() end loop

actually scratch that you can use it for animation but it wont work for moving it back

Turing:

x := x + 1 if x > 550 then x := x - 1 end if

Think very carefully about what your program is doing here.

Thank you for your help , but i was wondering, how would you make balls move at different speeds and locations from the left of the screen to the right, i got the whole background, and the pad at the screen. Basically the user controls a pad on the right side, they navigate up and down, and then balls come from the left side and with the pad the user is supposed to come in contact with the balls (moving at different speeds and locations which i need help with) then it returns to the left and dissapears

[Mark0213]

I just need help with a simple code for moving the balls from the left side of the screen to the right side of the screen at a pretty slow speed where the pad moves up and down and tries to hit the balls back,
so that it returns to the other side of the screen again, i got the pad and the background covered its just the moving balls i have problems with-Thanks everyone for your support it means alot, and im horrible at turing!

[Insectoid]

If you understand the most basic movement fundamentals of moving something across the screen, this should be trivial.

[Mark0213]

Insectoid to me its not

So mark, you are trying things too advanced if you don't. That's fine, but you need to spend some time on earlier topics.

ok, lets start with the very basics then. To "move" something across the screen, you take that something, and draw it at different locations, as the time passes by. (speed is displacement over time)

code:

for x : 1 .. 100     Draw.Oval(x,100,5,5,red)     delay(10) end for

This is the simplest way -- draw a circle a bunch of times, as it "moves" in a straight line. Different velocities (speed, direction) would dictate where to draw that circle next.

[Dreadnought]

Think about what is happening physically to the ball (Tony beat me to this)

If the speed was zero, then its position would not change. If it's speed is not zero then its position is changing (hmm... I smell variables) by some amount every frame (you could think in seconds too). So lets say you want the ball to go across the screen (500 pixels wide in this example) in 100 frames (normally animations run at 24, 30 or 60 frames per second). How many pixels do you want your ball to move each frame? The answer is a number of pixels per frame, which is a speed. (I'm sorry if this is obvious).

So now we got a ball moving at a speed. How can we make many balls move at different speeds? Well you gotta keep track of all of their positions and speeds. Arrays are nice for this (records too if you know them).

The general layout is

code:

loop   < clear screen >   < change positions of objects >   < draw objects at their new positions >   < time delay to regulate framerate > end loop

Also, if you don't already, using offscreenonly, View.Update and Time.DelaySinceLast is very good for making animations look nice.

Thanks guys, but for making it a ball, i must put a delay, and then draw tonys circle code, except with the colour of 0 at the end of the program?

[Mark0213]

but with tonys program when i try to make more then one ball move at the same time it wont even let me? im trying my best to understand sorry guys
and tony, how did you have x, when you didnt even declare it? or did you.. man i suck

[mirhagk]

That was a for loop, just so we know, what concepts have you covered?

And you need to make sure you draw both balls in the same loop, otherwise it will draw one, and then the other.
