Wow. Thank you SO much. You really helped me out! I'm super new to construct 2 so I'm still getting the hang of which events are the best to use for what.

I really appreciate it, thanks!

Hey everyone.

Here's my capx:

I'm trying to make a connect the dots game using a hex grid.

Long story short, I have a grid of "cell" objects with instance variable "IsEmpty"

The grid is filled with colored "Dots" which get destroyed when the player connects dots of similar colors.

When a dot is destroyed, its associated cell is set to empty.

I then have a function that selects the cell above, takes the dot inhabiting it, and moves it down to the empty space.

(Note: I want the dots to move in a zigzag like pattern down, so in a 6x6 hex grid, for example, a dot from the 6th hexagon will fall into the 12th hexagon; this explains my logic in selecting the dot)

I have a special handler for the top row, where empty spaces will be filled by "spawn" points above.

I would like this to keep repeating until the grid is full, but for some reason the dots stop moving even though there are still empty spaces on the grid.

I think I'm having trouble with checking the empty cells every tick. Not really sure what event to use. I tried "For each empty cell," and "pick cell where cell is empty," I even used a number variable to try to count the number of empty spaces, but that didn't seem to work.

Okay. I'm getting really frustrated now, because it SHOULD work but it's not.

I added a "NumEmpty" Variable that gets added to every time a dot is destroyed.

The system checks if NumEmpty > 0 every tick and is supposed to call the FillEmpty() function as long as there are empty cells.

However, when I run it and destroy some Dots, they only move once. and Spawn Dot isn't even called.

Here's the updated capx:

UPDATE:

I got them to move, but I'm now running into an issue where the last dots to move down move a cell too far and intersect with other dots.

Here's the capx:

Ok, I think I fixed it. Or at least made it slightly less broken <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile" />

(link removed)

I changed the way you select dots that should be moved (nearest dot which is above the cell) and I put the entire "For each cell" loop into a function, because I think it should not be executed on each tick.

I call this function after a line has been completed or after all dots have stopped moving.

It still uses pathfinding just to move dots, and not for its true purpose <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile" />

You should probably replace it with MoveTo behavior or Custom Movement or something similar.

Edit: Fixed a few more things, here is a new link:

Thanks. Unfortunately I can't open your file because I only have version 244. I assume 246 is a paid version?

I don't really think I need obstacles or solids, I just want to move the dot from one location to another.

Your link is broken.

Try posting it without the "https://"

Fixed. Thanks

Hey everyone. I'm new to construct 2 and I'm trying to work out an issue with path finding.

Right now I have a hex grid filled with "Cell" objects, each with an instance variable "Index" that's a number between 1 and 36 (It's a 6x6 grid).

The dimension of the grid is denoted by "DIMENSION" global variable (in this case, 6)

Cells also have an "IsEmpty" Boolean variable.

Initially the grid is filled with "Dot" objects. Throughout the game the Dots are destroyed, emptying their inhabited cell (Setting IsEmpty to true).

The distance between each dot on the grid is denoted by a variable "DistBetweenDots"

To handle this I have the following event block:

The nearest dot is selected, and we compare its distance to the current cell.

If there is no dot in the current cell, the distance to the nearest dot will be greater than DistBetweenDots/2.

Then, for all empty cells (excluding cells in the top row where Index > DIMENSION, because in that case new dots will be spawned)

I want to move a Dot from above into the empty cell. The dot to be moved is in the cell whose cell index is (empty cell's index - DIMENSION)

For this, I create a function MoveDot, with parameters (Dot's current cell index, target cell x, target cell y):

As seen above, I have placed debug statements to see where it goes wrong.

I am able to get to the point where a path is found. But once I call On pathfinding path found:

It does not execute. I know this because debug2 does not get set to "setting along path"

The logic seems correct. I'm not sure why the On "Pathfinding path found" Event is not triggering. Is the dot unable to find a path? Why would that be?

Here's the capx:

Thanks for any advice.

Thanks. Unfortunately I only have the free version so I can't use families.

But I will use your previous advice

Sure thing. Here it is:

Have you tried running your project in Debug Mode (Ctrl-F4)?

You'll be able to see what's going on - if the Line sprite gets created, which animation/frame playing and so on.

If this doesn't help, try adding debug output. This could be a text objects somewhere on your layout. Make it big, set text wrapping=Character. Use Text->Append text to print some debug information to it. For example:

MyDebug -> Append-> "ActiveDots:" & NumActiveDots

or

MyDebug -> Append-> "Line:" & Line.UID & " picked:" & Line.PickedCount

Or you can use Browser->Log action for this.

Yeah, I probably should have mentioned, I added a debug statement to the second touch event, and it triggered on the first click of a Dot.

Maybe it's instantaneously registering two touches?

I essentially did what the video said, but since the concept of what I'm trying to make is a bit different, I had to adjust it to fit my needs.

Here is the event sheet as it is right now:
