Thank you! I'm happy to hear that it's all feasible. I'll figure it out when the time comes.

Still unsolved. Got buried.

Glad you figured it out. I was just about to say that I can tell it has something to do with a process, probably a loop of some kind, that isn't being closed whenever the walls move because it gets slower after every subsequent move.

I have a few multiplayer questions.

I've read through https://www.scirra.com/manual/174/multiplayer and it gives me a sense of how multiplayer works (though not really how to implement it so far, but that's OK for now).

And then on https://www.scirra.com/blog/142/make-online-multiplayer-games-with-construct-2 I see the following bulleted blurb:

...

"-Support for both peer-hosted games (not needing a server) and centrally-hosted games (using a server)

-Official Scirra signalling server to connect players to each other"

Questions to be clarified:

1. On centrally-hosted games: Can I host my OWN server? Or must I use Scirra's central server? Is it better to just use Scirra's or would using your own probably be faster?

2. On peer-hosted games: any finished games use this? Is it like TCP/IP? Is it fairly reliable?

3. How feasible are these things to implement for someone without professional training in programming? I'm pretty thrifty with the C2 scripting system, for the most part, but mutliplayer seems like it must be tough to implement.

4. Slightly tangential question: It seems possible to have 4 different gamepads hooked up to the computer and use them all in local multiplayer, right? I know C2 has gamepad support, but does it have reliable multiple gamepad support?

From https://www.scirra.com/manual/143/gamepad

Multiple gamepad devices can be connected to a single computer. To differentiate between them, most actions, conditions and expressions in the Gamepad object also take a Gamepad parameter. This is a zero-based index of the controller. For example, 0 identifies the first controller, 1 identifies the second, and so on. This allows you to make multiplayer gamepad-controlled games.

Any guides I missed that expand on that?

Thanks for the tips, everyone. And for some reason my first layer was NOT set to transparent. Weird. But now I know!

Yeah I ended up figuring it out. Blows my mind that it isn't set to be transparent by default... Weird as heck.

This is so stressful. I haven't used C2 in a while and I'm having a problem I remember having when I first tried it out 2 years ago: I have several layers, each layer has things on it, but only the top layer is actually visible.

Yes, they're all checked as "visible". Default settings all the way. Why can't I see anything on the other layers unless I drag those layers to the top?

Seems to me a long time ago there used to be an "Advanced Platforming" plugin or something that included features like wall climbing, double jumps, ground pounds, etc. Can someone please help me find it? I checked the Plugin list and it isn't there anymore that I'm seeing.

Hi, so I was thinking about making a fighting game... Would love for it to have AI/vs computer mode, but for the life of me I have absolutely no clue how to approach that. Is it possible? Has anything similar been done? Thanks for your input!

Oh duh. Gees what a rookie mistake. I haven't used C2 in like a year and I forgot even the basics. Thanks man.

Please check the .capx

The layers are all setup correctly, I think. I'm sure I'm making a mistake that I'm not seeing. I've got this weird issue where my background layer is visible but all objects on the foreground layer don't appear. Yes, everything is "set to visible" and there shouldn't be any issues with opacity. I've tried deleting the background entirely and keeping the foreground but for some weird reason the foreground sprites don't show up. What am I doing wrong?

I'm afraid you're right. Still, I'd like to learn how to do it myself one day, but a mathematician is something I am not.
