Supertux: Local 2+ Player Multiplayer

[Karkus476]

A few steps to this:

• [ ] Format
  
  
  
  • Split Screen
  
  
  • One Screen
  
  
• [ ] Second player (with sprites)
  
  
  
  • Penny?
  
  
• [ ] New control configs for new player
• [ ] Play campaign?

Nice.

[Karkus476]

Here is an (outdated) diff which may serve as inspiration. https://github.com/SuperTux/supertux/blob/master/contrib/supertux-coop.diff

[brmbrmcar]

Multiplayer should be just Tux and Penny for now.

[tobbi]

We need proper sprite assets first...On the other hand: The story features Penny being abducted by Nolok. So she probably can't be played...

[Karkus476]

I am working to update this so the diff does work, after which we can have polls etc. regarding this. After M2 is the ideal time to implement it too, I would love to be able to play with others.

[Karkus476]

Is it agreed that this should be one screen (rather than split-screen)? That's what I'd prefer.

[brmbrmcar]

Nolok can just be like a "boss". Don't keep the same story.

[Karkus476]

No. I want to be able to play through the story too, with 2 players.

But that would have to wait, because there is no other player in the storyline. And also, what about once Penny is freed?

[tobbi]

So far we've been avoiding that ;)

[Karkus476]

It's not that complex, we just need a new character.

[brmbrmcar]

But to the story line? There was this one character that could jump high, who was that?

[Karkus476]

They are just another hero, who wants to help Tux

[brmbrmcar]

Fluffy. http://supertux.lethargik.org/wiki/Fluffy

[Karkus476]

I don't think the characters should be different at all.

[brmbrmcar]

What do you mean?

[Karkus476]

Fluffy would have different abilities to Tux, which is unfair, and wouldn't work

[brmbrmcar]

It is like that in virtually every multiplayer game. You just have to modify the levels to make it fair.

[Karkus476]

Nah, I say we keep them the same, otherwise the slower would be left behind.

[brmbrmcar]

You see how difficult this is?

[Karkus476]

Only because there is a disagreement. This is why I opened this issue, so we could make some decisions now rather than later

[brmbrmcar]

Yes, but the point is it is impossible to meet all this criteria.

[Karkus476]

Great idea, let's give up before we've even begun?

[brmbrmcar]

No. Just something has to be sacrificed.

[brmbrmcar]

No, part of the criteria.

[brmbrmcar]

A new character is the best bet, but I am a bit unsure.

[Karkus476]

Notable page on the old wiki.

I'd agree with @Karkus476 that this should be one screen (the camera can just zoom out so both players are always visible). The other ideas are not important for now, fixing the two-player-objects patch is more important.

[TriVoxel]

What if we there is just another open-source character used? Like Tux is linux, what about Suzanne for Blender, or something like that? Kind of like Super Tux Kart used multiple open-source characters.

[christ2go]

There are some design decisions to be made.

• [ ] What happens, when one player dies? (Does it matter if it is the secondary player?)
• [ ] Should the camera have a maximum zoom, at which point a marker (similiar to when Tux is above the screen) would be displayed.

[ildar]

I've seen Nintendo Mario two player game on YouTube. I don't remember about
deaths but zoom was dynamic.

My ideas and thoughts:

Adding/Removing second player: Should be a menu from within the game level that says: Add second player. Adding will spawn Player 2 wherever Player 1 is. Then, from the menu, the second player can be removed from the same menu where they were inserted. If the player exits to the menu or to the worldmap, Player 2 will disappear.

Controls: Most likely WASD for arrow keys, maybe something like J for jump and S for action? Pressing the pause button will still pause the game and both players can use the same menu.

Format: For simplicity, should follow Player 1 and if Player 2 goes outside the camera zone you can't see them until Play 1 catches up with them.

Second Player: Should be Penny, but also multiple other characters. They all have the same power as Tux. Needs a menu for 2nd Player player sprite selection, but Player 1 will always be Tux.

If one player dies: Respawns wherever the other player is. It would add an advantage to having two players ;)

Powerups and Coins: Coins will be for both players collectively. Each player will have separate powerups though.

Collectibles and Enemies: Coins can only be picked up once, enemies can only be killed once, etc.

I hope you guys enjoy my ideas! :)

[brmbrmcar]

Surely controls would be defined by the players?

[weluvgoatz]

Yes, hopefully... I'm just suggesting default controls.
