My Flettners wont fly :(

[Coroner47]

This might help you. I found this a while ago. Ive never messed with environmental vehicles myself. The bottom of the document should give you a good idea of how they work tho. Also, Apache has some environmental vehicles in his DC Unauthorized mod you can check out. I'm sure his mod is in the "Mod Download" section of the forum. Credit goes to Zeuser[RET]

Environmental vehicles
By: Zeuser[RET]

Back when I was coding for DCX I put forward the term "Environmental vehicles" which simply means that a vehicle is just part of the environement to enahnce how a map feels and can't be flown by either bots or humans.

If you try the latest DCX (0.9) you'll find environmental vehicles on the Sniperfest, Lost village, Lost village Brit and Paintball maps.

A few types of environmental vehicles include:

1 - A pair of Medivac blackhawk helicopters that simply do a fly-by
2 - The same pair of Medivac Blackhawks but are used by the Bots as airborne spawnpoints. They will then parachute out of the heli when flying over landing zones.
3 - Save as above but with Chinooks for the British maps.
4 - A C-130 that swoops down and flies away.

And another type I just coded yesterday:

5 - A pair of SU-25s that fly-by and drop bombs.

Cool factor

What's cool about the environmental vehicles is that they spawn and simply fly straight on their own. They're not attached to a rotational bundle or anything. So this means you can shoot them down or even bump into them. And sometimes they can even run into a hill or building on their own. Pretty cool!

How it's done

Lets take the SU-25 and convert it to "environmental". We'll just make a copy of the SU-25 and make it environmental. Here's the code:

Notice all the bolded parts.

The idea is to use the SU-25 almost as-is. But you must remove the entry to prevent a player or bot from entering the vehicle. Of course the camera, seat and a few other objects can also be removed. but it does work in its current form.

Then you'll noticed that I jammed the elevators at 5 degrees up rotation so the SU-25 has a tendency ot nose up a bit. This prevents it from crashing into the ground on take-off.

The important part ot make this work is to use the "Rocket" type of engine so it'll instantly go on as soon as it spawns. And then adjust the minroation, maxrotation and acceleration in such a way that the engine gets max thrust ASAP! I also double the engine power to make sure it flies forward soon as it spawns.

You'll notice the weapon changes as well. it's set to drop bombs a few seconds after it spawns. I'll try to get that thing to randomize as well.

Use on a map

What I usually do is put a spawner in the air on the edge of a map pointing inwards towards the center of the map. On certain maps like Lost village I point them towards the landing zones. So unless they're shot down or bumped into, the helis fly over the landing zones.

I usually set the spawn times as random so it doesn't become too predicatble.

On some maps, like Bulge, I put the spawners on rotational bundles. Combined with the random spawn times, the vehicles are hard to predict. You never know when they'll come and from where they'll come.

Experiment with the concept a bit and be creative. Add spawn points, make the vehicle go round and round, add bot gunners etc.

The important part is that the vehicle is autonomous and can react to weapons and collisions. It looks more natural that way.

[freddy]

you may want to try

Code: Select all

ObjectTemplate.setAutomaticReset 0

[Dennis|8749236]

your engine type is Rocket, that's why it won't fly(i got that problem too, when i was writing ME109TL's engine part...i thought use ETRocket it will go faster...-_-|||)

[freddy]

try activate the Flettner_HoverEngine, might work better.

the setEngineType c_ETRocket type is used as it starts with full throttle even with no input from any player

[Dennis|8749236]

really？？？
lastt time i write a engine use c_ETRocket it won't fly too...

[freddy]

yes. there are two types of engines that "starts by them selfes"

c_ETRocket - Identical to c_ETPlane, except that it does not require input, the engine starts running at creation
c_ETTorpedo - Identical to c_ETSea, except that it does not require input, the engine starts running at creation

http://dzn.org.pl/mdt/scripting/ObjectT ... .shtm.html

but however they doesn´t have this this line of code

Code: Select all

ObjectTemplate.setAutomaticReset 1

and im not sure if/how that can affect if you changing an existant engine and/or building your own.

This is used to modify the effect of a key or button on the pitch, rotation, etc. If set to 1, it resets the throttle to zero after user input is removed.

http://dzn.org.pl/mdt/scripting/ObjectT ... .shtm.html

i know if you have a "selfgoing" vehicle and get into the drivers position, it will stop as soon you get out from driver position.

[Archimonday]

If this is completely map side, attach the prop rotational bundle to a strong rocket engine (with no effects, and a helicopter engine sound) pushing the craft forward. Then attach a much weaker rocket engine somewhere on the front, or middle of the plane to keep it from coming down.
