This is my first time planning, and I have a few questions about it:

1) How do I get infantry to enter starfighters?
2) How do I get those fighters to take off?
3) How do I get fighters to travel to a higher/lower "altitude" using planning (raise hub? connection?)
4) How do I make fighters roll?

Thanks in advance.

look in the docs - "Getting Started-Space notes"

I did, it told me to redirect to FlyerSplineFollowing.txt. I read the whole thing through and it didn't answer my questions. How do I get infantry to enter starfighters, how to launch those starfighters, and to get a path that directs starfighters to climb to a higher altitude?

Well, try making a path to the starfighters?
The infantry normally have this "OMG A VEHICLE" instinct that kicks in when they spot one, forcing them to head right to it.
In my experience, anyway.

Oh look what i found in the FAQ-thread: forcing player into vehicle
you should probably do a bit more research
and it is no coincidence that "research" has "search" in it

That's for forcing all players to spawn into vehicles.
He wants his AI to walk to the vehicle and get in.
I think.
EDIT: Oh, and, do you have landing regions?
EDIT2: Wait, is this a land or space map?

i thought he meant the player since the ai usually gets into vehicles autoamtically, as you said

The questions are in relation to planning.

1) Vehicles have a call radius defined in the mission lua. Infantry will only try to enter a vehicle if they are within that, so you only really need to do planning that leads them to and from the hangar.

2) A pilotable fighter takes off on it's own, usually within seconds of a bot entering the pilot position. This is hardcoded AI behavior.

3) Hubs and connections have infinite height. It's in the docs. If you want a fighter to fly at a specific "altitude", use flyer splines, as they offer precise controls. You should take another look at that doc, since it opens a lot of possibilities.

4) Like #2, it's something bots do on their own. I'm pretty sure this is also hardcoded.

Thanks again MercuryNoodles. My only problem is that I don't understand what FlyerSplineFollowing.txt is saying. I use this in where?

You use CR splines (if I remember correctly) in ZE to create paths for your flyers. There are properties you can attribute to these paths and their nodes in ZE. There are also a few odf lines that can be used for addition control. It's all in that file. Use a sandbox map to see what you can do with them, and that should help you understand how they work, if you're finding the doc too confusing. It's a lot of info to take in at once, so take your time, and reread it as needed.

Ok, thanks again.
