Help on Growing Ovals?

[JHybrid]

I need to make 3 ovals grow from its centre point at the same time. I tried

code:

loop     var wFoilage1 : int := 100     var wFoilage2 : int := 105     var wFoilage3 : int := 85     var hFoilage1 : int := 80     var hFoilage2 : int := 70     var hFoilage3 : int := 110     drawfilloval (560, 300, wFoilage1, hFoilage1, 12)     drawfilloval (600, 250, wFoilage2, hFoilage2, 12)     drawfilloval (625, 280, wFoilage3, hFoilage3, 12)     delay (10)         wFoilage1 := wFoilage1+1     wFoilage2 := wFoilage2+1     wFoilage3 := wFoilage3+1     hFoilage1 := hFoilage1+1     hFoilage2 := hFoilage2+1     hFoilage3 := hFoilage3+1 end loop

But I'm thinking that doesn't work. Can anyone help me on how i could make them grow outwards?

loop
var wFoilage1 : int := 100
...

what is the value of wFoilage1 after the loop has executed N times?

ugh I think I've done something wrong. Now the code is

code:

loop var wFoilage1,wFoilage2,wFoilage3,hFoilage1,hFoilage2,hFoilage3 : int := 1 drawfilloval (560, 300, wFoilage1, hFoilage1, 12) drawfilloval (600, 250, wFoilage2, hFoilage2, 12) drawfilloval (625, 280, wFoilage3, hFoilage3, 12) delay (35) wFoilage2 := wFoilage2 + 1 wFoilage3 := wFoilage3 + 1 hFoilage1 := wFoilage1 + 1 hFoilage2 := wFoilage2 + 1 hFoilage3 := wFoilage3 + 1 if wFoilage1= 100 and wFoilage2= 105 and wFoilage3= 85 and hFoilage1= 80 and hFoilage2= 70 and hFoilage3= 110 then exit end if end loop

What I want is 3 dots growing out to the dimensions I've specified. :[
I don't know if I've made it better or worse but this time nothing moves. Just the three dots that are supposed to grow... but don't. Am I missing something to make it move? I've quite new at this. My teacher doesn't know half a thing about Turing and he's making us learn it based on analyzing other codes.

You still have to answer the same question.

Lets take it step by step

- the loop starts
- wFoilage1 is created with a starting value of 100
- some other things happen
- the loop comes to the end and starts again
- wFoilage1 is created...

What is the value of wFoilage1 when you drawfilloval for the second time?

[JHybrid]

I was hoping the loop wouldn't repeat. :\

What I want to happen:
-loop begins
-wFoilage1 = 1 and starts growing along with the other variables
-wFoilage1 reaches 100
-exit
-loop ends and does not start again

I was thinking "if x = .....then exit" would stop it.

But still right now the ovals are not growing at all. ><

[Just realized I spelt "foliage" wrong the entire program..]

Though that's the purpose of the loops - to repeat a block of code multiple times. If you don't want something repeated, put it outside of the loop.

do you want to declare variables multiple times?
do you want to draw ovals multiple times?
do you want to change values multiple times?
etc.

The reason you're having the problem is the first line of the loop.

Every time the loop repeats, the variables are all reset to 1, then the ovals are drawn, so nothing happens.
