sv_gametype mod + dm/tdm/ctf ?

In short: you can't.
You have to *mod* the source for that.

Remember the 80s - good times

So the "MOD" gametype from the official Teeworlds only supports DM? I've never though about that, it's a bit strange indeed.

Well I think the mod gametype was never intended to be used as a way to tune the server physics but rather to give modders a base to create their own gametype.

And what's the purpose for forcing people to play with the slow physics ?
Is there a real reason to remove a usefull option ?

Ah, I understand. In fact, when you create something for a special purpose, you associate it in your head and can't dissociate it. It's like "sv_gametype is for changing the game mode" : you cannot dissociate "mod" and "tdm/ctf". Shit

You have to understand that you have the power to dissociate things : if people find an option interesting, keep it and don't feel jealous because they explain you did a mistake by associating things where you should not have. It's a common thing in the dev world !

People will love your work if you make an effort ; they will abandon your game if you don't listen to them. I understand you're not here to satisfy everyone's will, but if you implement a thing, just don't wipe it because the definition of it was inflexible. By the way, I know you don't give a shit but I will abandon your game if I can't tune it no more or can't play tdm/ctf in decent way next weeks/months.

1. What kind of issue ?
2. How can tuning variable can mess a server. It's difficult to imagine how we can "mess a server" just by changing the speed or gravity.
3. And if someone mess his server : a) he just has to take an old backup of cfg and this is good , b) You're not forced to answer everybody on the forum

I think it's possible to keep tuning + using mods. I would like to learn how to code/compile your game and do a fork, if you accept.
