If you're down to invest a little time I highly recommend Harvard's free CS50+ class

You don't even have to go very far in it. Doing a few weeks of this will give you a very strong foundation and teach you how to think like a programmer

> To your first question, you can use Scirra's signalling server. If you want to have a dedicated host for the game, you simply need to keep a session running

It's a bit confusing for me. Do I need a dedicated server to have a multiplayer game running? I am assuming this is not the regular host where I host my website, for example. If so, I can host the game and still use the Scirra's signaling server for free?

The multiplayer plugin uses P2P, where the first player to enter the game is the host, and the rest are peers, so you don't need a dedicated server. Yes, you can host the game on your website and still use Scirra's signaling server

If you're going to have lots of objects that disappear when not in LOS, you can create a Family called LOSFamily and put all the objects you want to disappear in it

Then, you only need 1 event

+Player has LOS to LOSFamily

->Set LOSFamily Opacity to 100

I've gotten them to work. Are you getting any kind of error message?

Has anyone had any success with this?

In this condition, you have it set so that if Keyboard = 1 AND if Gamepad = 2, then activate both the keyboard and the gamepad group

You should separate these into 2 conditions

If keyboard = 1, activate keyboard group

else

If gamepad = 2, activate gamepad group

In the "Pathfinding" behavior under the Enemies Family, you can change "Solid" to "Custom" in the dropdown menu

Then, just make an event at the start of the layout that does Enemy Family > Pathfinding > Add Obstacle (Enemies)
