i am trying to develop this type of game so i dont want

to write hitTest on every clips , is ther any other logic which can help to connect the pipes and change their color when they are connected with each other , pipes can be randomly placed within tiles…any help

i’d say use an array

for eg;

```auto
var pipes:Array = [
[0, 0, 0, 1, 0, 0, 1, 0, 1],
[0, 0, 0, 1, 1, 1, 1, 0, 1],
[0, 0, 0, 0, 0, 1, 0, 0, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1],
[0, 0, 0, 0, 0, 0, 0, 0, 1],
[0, 0, 0, 0, 0, 0, 0, 0, 1]
];

```

Where the value 1 will represent a block of pipe; then check if there’s a value of 1 before or after, or in the corresponding items in the previous or following arrays.

Hittest? I wouldn’t have even thought of using hittest for this, so I really don’t grok how you’re approaching this.

I would have a square array of pipes, but not just numbers like nathan did. I would make a pipe class, with a rotate method, and four methods that return values for top, bottom, right, left. And also a change colour method, which is passed a direction and a colour value. If it is open in that direction and it is not already that colour, it changes colour and calls the change colour method on all tiles it is connected to.

O I didn’t look at the link - so it’s different to what I originally thought - If I get time I’ll make a demo

That’s a pretty cool monologue you have there.

I think you should post the “solutions” you have for people that might find this topic in a search, looking for the same problem.

That’s if you are only talking about binary array… You can use rest of whatever is flash’s integer values.

Considering the pipes rotate in one direction, this is very easy.

You can say,

0 = empty space  
1 = horizontal pipe  
10 = elbow pipe  
20 = cross pipe

then,

2 = horizontal pipe in vertical position  
11 = elbow pipe from top to left  
12 = elbow pipe from left to down  
13 = elbow pipe from down to right  
14 = elbow pipe from right to top

and you can even make use of other numbers…

111 = elbow pipe from top to left in blue color  
211 = elbow pipe from top to left in yellow colour.

… so in the end, it’s all how you set the convention.

When you are checking if a path exist, you just have to check if one of the gas outlet is linked with, say, any pipe line with values greater than 100 or 200…etc.

So to use the array example above, following will be a winning combo

```auto

pipes:Array = [
[101, 0, 0, 1, 0, 0, 1, 0, 201],
[0, 0, 0, 1, 1, 1, 1, 0, 201],
[0, 0, 113, 101, 101, 101, 101, 101, 201],
[101, 101, 111, 1, 1, 1, 1, 1, 201],
[0, 0, 0, 0, 0, 0, 0, 0, 201],
[0, 0, 0, 0, 0, 0, 0, 0, 201]
];

```

Thanks for this reply , but its ok that you can place pipe of any size either “L” shape or “U"shape , but the problem is that whenevr you click on 'U” shape U should move and should not call “L” shape, here is my fla …chk it.

whenver you click on “I” shape “I” should move in corresponding direction and it should not call U shape …

if you look at the attach file

a pipe will change colour if it connects to the one on the left but not dependent on touching one on the left or right

to check right is roughly the asme code but target is +1, to check up is target -10, to below is target +10

i might do more at a later date …if i feel i am going in the right direction
