But larger variants don't require a small map? And I'm looking under the large map. My current guess is the map is too large and I have to do something weird where you stitch multiple maps together?

It kind of looks like your mapNames has a transparent background. The background should be white.

How manny territories are on your map?
200 is a limit for territories that needs to be recolored (land/coast)-types, as you can't save the map as an indexed-PNG with more than 256 colors (it's a really old format).
If it's more than 255 minus number of countries you need to create more than 1 map and I need to stitch this together. And 200 - 256 I usually need to reset the colorpalette after the territories are recolored so there are enough colors for the units left.

Just checked your file.
As I guessed, it's >256 colors. You need to split the map in more parts.

PS: I have adjusted the thread-name, as we have a lot of new variant-development going on at the moment, and I encouraged everyone to create his own thread here.

The "all the variant development discussion gets mushed into a single thread" era is over???

At least for these "under active development on this site..." :-)
We have 3 new 1st-time developers at the moment, and the errors/problems are usually all the same, so I encouraged everyone to create an open development thread to shre the problems/ideas.

Once I make split the map into two, then I should only need to adjust the code in "drawMap.php" right?

I think the MultiLayerMap_drawMap class from the Divided States map should work? (or at least that's the code I pasted and modified for the new drawMap.php

So all variants are created equal, but some are more equal than others.

For security reasons you can't change the code directly. I need to do this or at least approve your code.
As long as there are no unreasonable request I can do this for you.

But if you want to test all the code-changes on your own, you need to setup your own server (a local XAMPP on a Win10 machine is sufficient).

I fixed the problems with your map.
1. Wrong graphics-format. I changed them to indexed-PNG.
2. You've put the bottom overlay on top of the top-overlay.
3. The smallmapNames-overay had a transparent background. Without some code-change this turned to white (And again, wrong color-format).
4. Did some adjustments to the drawmap.php.

Everything loads now. But IMHO the mapsize is really too big...

I don't believe there's a way around a big map with this one, though, right? Or do you mean it should be split into different parts?

IMHO the problem is just the imagesize. Splitting worked without any problems. But the territories are really large drawn at the moment too. The upper left territory takes half a screen unzoomed. You can hardly spot the large uniticons.

If you can't get more than 20 territories unzoomed on a 1920x1080 screen there might be usability-problems.

Awesome! Thanks so much!!

Noted on the mapsize, I'm definitely going to keep that in mind for the future! If you think it will be a problem (either from a usability standpoint, or from a actually getting everything to run standpoint), then I can work on finding a way to shrink everything down without changing the colors of the pixels.

Are the oceans turning up pink a result of the preview screen being weird? (It loads correctly in the map screen)

I was going to have the custom units to scale with the map size, but maybe you're right and I should just figure out a way to shrink everything. A bit of a pity because the detail is pretty cool :(

I shrunk down the map, and then indexed them, but somehow the bottom map isn't showing up. Not sure what I did wrong?

I know the code is a bit strange. The TopMap needs to be set to transparent for this to work (instead of plain-white like the names-overlay)...

(Or you can change the drawmap.php to replace the white with transparent)
PS: I did replace your graphic file already

Alright! Sweet!! You really deserve more credit for how on top of everything you are! (It's really nice!)

After starting to add territories (and rename existing territories) to the variant, there are still references to "terr1" somewhere? (At least that's what the error message in the preview claims) The map loads perfectly inside the map area!

Yeah. I see the problem with the preview. I will check this. Might be a problem with the preview-tool.
And I need to check why it's not coloring the land/coast territories. The graphics are really tricky, esp. for large variants. It's quite an old code we are working with here..

Just tried to open up PitsOfHorror and couldn't find it in the list of variants. (When I refreshed an existing page it changed to the CubanMissleCrisis variant. Any ideas on what might have happened?

I'm not sure, you should ask the mods

Yikes, maybe it got accidentally overridden when Cuban Missile Crisis was added?

That looks like it: CubanMissileCrisis ID is 140 (highest ID is 144 i'm pretty sure), but CubanMissileCrisis got created most recently. I think PitsOfHorror got overidden when CubanMissileCrisis got put in.

*highest is 147

You should contact a mod

There was no development on the PitsOfHorror variant for quite some time, so I disabled it. Sorry.
I will check this at the weekend.

Yeah I took a break from it, but then I started again last week. Whenever you get around to it I'd love to continue working on it!
