PostPosted: Thu Oct 28, 2004 9:27 am   Post subject: background

can someone help me make a background for my animation/game thing. im trying to make a ufo fly above a town at night time when you press a direction. here is my code so far.

code:

%kyle's ufo thing

var x,y : int
x:=100
y:=100
var chars : array char of boolean
var ufo :int

%draws the ufo
drawfillbox(15,15,50,20,red)
drawfillbox(20,20,45,15,9)
drawfillbox(20,20,45,25,8)
drawline(15,5,23,15,7)
drawline(23,15,43,15,7)
drawline(43,15,50,5,7)
drawline(50,5,15,5,7)
drawfill(35,10,yellow,7)
drawbox(15,15,50,20,7)
drawbox(20,15,45,20,7)
drawbox(20,20,45,25,7)

%takes the picture of the ufo
ufo := Pic.New (15,5,50,25)


loop
Input.KeyDown (chars)

Pic.Draw (ufo, x, y, picCopy)
    if chars (KEY_UP_ARROW) then
    y:=y+5
    end if
   
    if chars (KEY_RIGHT_ARROW) then
    x:=x+5
    end if
   
    if chars (KEY_LEFT_ARROW) then
    x:=x-5
    end if
   
    if chars (KEY_DOWN_ARROW) then
    y:=y-5
    end if
           
            drawbox(x,y,x,y,red)
            delay(50)
cls
end loop

Ok...

For this you'll need to look up on View.Update, and flicker reduction. Conventiantly, there just happens to be a great tutorial on the very subject! Amazing what you'll find in that section:

No more screen flickers! by tony

The idea is that you'll consider the screen in two layers. You have the background, and the foreground. Each frame, you redraw the background, then you update the position of the objects (foreground) over the background. Then you View.Update the whole screen - effectively producing a clean animation.
Enjoy.

Here is a bit of an update for flikering

use the setscreen command
code:
setscreen("offscreenonly")

then after every time it draw the object use View.Update

I think he wants people to make a background for him. I am assuming using drawline and drawoval and stuff like that.

If that's what you want, search for Pic~2~Code by Delta, it's quite useful.
