Would it be possible to make an Invasion mode like Halo Reach? I was thinking about attempting it.

I'll shoot you down before it's too late.

No.

You would need to re-code part of halo's blam engine, and also script extra mods and changes.


e.t.c

I'm not sure what all the invasion includes, but sure. Have some trigger volumes about, that if a team stands in long enough, they capture. As they capture more points, spawn more weapons and vehicles on that teams side (use either .weapons or .effects that create the weapons, instead of item collections so you can control them and spawn them manually). Etc.

For correctly determining the team, you'd either require them to play CTF, or use OS. With CTF, the teams actually correctly spawn at their team spawn points, so spawn them off the map, and when they spawn, simply mark them down in a global variable for that team, then teleport them into the map (teleporting them in, also allows you to 'unlock' spawn points through the games progression). Or, with OS, you can just check any units team, and even directly check whether the gametype is set to teams.

But you would have to script the cut scenes. e.t.c

And cut scenes in an mp environment is impossible.

Don't see why a cutscene can't just be left out.

Wouldn't really be staying true to the invasion game type then.

Do a cutscene the same way you'd do one in SP, just either use a biped crush, or place all players in one room, to convey to the clients to show the cinematic. When the syncing condition ends, the clients end their cutscene (regardless of where it is). If you simply move all the players to one room, then you can attach-detach some scenery to each of them beforehand to track their previous location, them simple attach-detach them back to it to return them to their places.

This is gonna be my first ti make a mod with Halo CE at all. I wonder what tools do I use for modding?
