Missile Help in Missile Command

[MOUSECORD]

I am making Missile Command i have most things completed except the core of the game (the missiles) that drop from the sky... i just can't figure out a way to program the missiles to fall... or anything ... i need some insight on how to make lines drop gradually from the top if someone could help it will be greatly appreciated... Thanks

this should be in "turing help" not "turing submissions", here is where u submit your programs.

drop as in

code:

View.Set ("offscreenonly") var y : int := maxy loop     exit when y < 0     y -= 5     Draw.FillOval (100, y, 5, 5, red)     View.Update     cls end loop

?

yeah i guess that kinda works i didn't think to use a oval i was thinking of using drawline hmmm Ahhh its confusing believe me lol i'm sucha noob to this i guess but i was attempting to make them gradually go down u kno? that is like a spec and i attempted to put a delay.... and it didn't seem to work ya kno not sure

[Tony]

you might want to get a hold of valor

[aside]

replace the drawfilloval with the procedure you use to draw your graphics, then use delay() to make the program run slower.

k yeah i got that like... draw.filloval stuff going down like straight down thx for the good start its going good now i think now... i never thought of using ovals... i thought of using lines... i'm not sure if u could use lines also... anyone know if u could use lines too... hmmm quite complecated mb its easier then i think it is... i'm over thinking it i think.... i made it like this.... :

View.Set ("offscreenonly:640;400")
var y : int := maxy
var y1 : int := 21



loop

%exit when y < 0

if y <= 0 then
randint(y1,0,640)
end if

y -= 1
Draw.FillOval (y1, y, 2, 2, red)
delay(10)
%View.Update

end loop


( i know it dosn't work....)
but i'm making it so it makes a random y1 value so it starts in a differnt time each time... but yeah i kno it kinda draws random dots everywhere... i gotta fix that LOL... maybe theres a way to use a line where the lines made at the top ... then it goes down from the one side ... not sure anyone seen that...

[aside]

you can just replace the part drawing the oval with any graphics you like, it doesn't matter if it is a line or circle or oval or box, but it would be better if the missle is large enough to see easily.

Okay i got a new idea from valors i studied his game and i see that there is a line drawn at the top horizontally... right then the x2 y2 are subtracted right? so it seems to fall from the sky in a matter of speaking do u see ... well check what i've done so far....

code:

View.Set ("offscreenonly:640;400") var x1, y1 : int var x2 : int var y2 : int loop     randomize     randint (x1, 0, 640)     randint (y1, 400, 500)     randint (x2, 0, 640)     y2 := 0     loop         drawline (x1, y1, x2 - 1, y2 - 1, 4)         cls         delay (1000)         exit when y2 > 0     end loop end loop

Okay so when u run it u don't see anything i can't get it to show the missile falling can neone see why is there a tweek i need to do...???

[aside]

you used cls right after you draw the line, so it is erased before it is shown. move the cls before the drawline

[MOUSECORD]

now it just shows the line where its desination will be it doesn't show it going to it... hmmmm

[aside]

well, your variables (x and y) are not changing, so of course it will be the same line forever. change the variables.

[MOUSECORD]

yeah but see i'm making x1 and y1 being at a fixed state at the top of the screen and then x2 and y2 are - 1 so that those two points move down the screen u see??? does that make any sense?/?

[aside]

yes, you made the x2 and y2 -1 when you are using it, but you are not changing the basic value of them. if x2 is originally 6, then you will have an x value of x2-1=6-1=5 always, use x2:=x2-2 or x2-=2 to actually change the value stored inside the variable
