Re: Effects showroom!

Why485

Here is the actual engine effects used in the video. They’re pretty specific purpose, but they are here if anyone wants to use them directly or as base code for something else.

I also haven’t tested it, but I get the feeling that it won’t work properly in multiplayer. As far as I’m aware, the state of a player’s engine does not get sent to the server or other players. Meaning to a player observing another player’s engine, the engine will always be at idle. In this case of this effect, idle looking like the engine is completely turned off.

The settings I used in the engine_equip file were these:

flame_effect = gf_br_largeengine03
trail_effect = gf_br_smallengine03_trail
trail_effect_player = gf_br_smallengine03_trail

So, what do you do there? Forward motion is done by the engines, reverse motion by the thrusters? In other words, no forward motion assist by thrusters?…
That’s so simple yet so ingenious…

Gisteron

i recognised the effect disappears, when you shut down the engines. is that managed by the effect? how?

Yeah that’s pretty much it. That and some modifications to the battleship handling to make it feel like you’re really throwing weight around when you move it. Those thrusters have to work to move the ship.

That’s done in the ALE. Vanilla effects do the exact same thing, they just don’t completely shut off when you throttle down to 0.

I don’t entirely understand what’s going on here, but this is how I made what I did work.

Emitter_Frequency = {
Flag = 4

Entry = 0.0000000000000000, 0.0000000000000000
EFlag = 0
SubFlag = 1
SubEntry = 0.0000000000000000, 0.0000000000000000, 0.0000000000000000, 0.0000000000000000

Entry = 0.0000000000000000, 6.0000000000000000
EFlag = 0
SubFlag = 1
SubEntry = 0.0000000000000000, 0.0000000000000000, 0.0000000000000000, 0.0000000000000000

Entry = 0.0000000000000000, 100.0000000000000000
EFlag = 0
SubFlag = 1
SubEntry = 0.0000000000000000, 50.0000000000000000, 0.0000000000000000, 0.0000000000000000
}

Of interest is the three Entry lines. At least in the context of an engine, they set points on a graph of how much the frequency should be at a certain throttle position.

For example, at 6% throttle, the emitter emits at a frequency of 0.

Entry = 0.0000000000000000, 6.0000000000000000
EFlag = 0
SubFlag = 1
SubEntry = 0.0000000000000000, 0.0000000000000000, 0.0000000000000000, 0.0000000000000000

Likewise, in this snippet, it tells the emitter to emit at a frequency of 50 when at 100% throttle. The Freelancer engine does a simple linear interpolation between these values. Think of it as plotting a graph using these given points.

Entry = 0.0000000000000000, 100.0000000000000000
EFlag = 0
SubFlag = 1
SubEntry = 0.0000000000000000, 50.0000000000000000, 0.0000000000000000, 0.0000000000000000

Gisteron

as we are on it: the frequency, is it particles per second or how are they calculated?

FriendlyFire

Particles per second, randomly generated.

Hi mates,

This is a question aimed at Why485 but hoping anyone maybe able to give the answer. Im currently trying to recreate the reverse thruster effect shown in a previous post and come up with a problem. With the engine powered up (not killed) everything works fine, the ship goes forward with the engine and reverse when thrusting. The problem I found was when the engine is killed, the thruster works as normal ie. it powers the ship forward. Is this a known problem ? Any advice would be appreciated.

I think what you need to do is go into the cmp for the ship and flip the hardpoint that you’re using 180 degrees. I wish I could remember which axis that is, those always confused me…

Gisteron

yea the axises in the hardcmp on the rotation are entirely wrongly written in the program layout. the first one is z and not x, the second is x and not y and the last is y but not z (while we agree that y is, like in physics, the up-down axis and z is the back-front one).

I’ll be honest and just say that doing such a thing never occurred to me. In making the reverse thruster thing, I never killed the engine and tried to fire a thruster with negative thrust.

Thrusters with a reverse thrust may very well do just that with how they were coded into Freelancer. Short of a hex edit, I don’t think anything can be done about that if it happens entirely as you describe.

To prevent that from ever being an issue I suppose you could disable engine kill… I was never really a fan of it, and Itano Circus actually does just that. In IC it messed up the flow of things so the player just isn’t allowed to engine kill. (Disabled the key for it.) I’m not sure how practical a solution that is for your mod though, as it is a global change.

is anyone interested on a hardpointeditor.exe of the version 1.0.0.18 where this is fixed? just did it a few mins ago. hope SHSAN wouldn’t mind…

Quarks

Yes please, but why did you modify 1.0.0.18?

Gisteron

because the .23 version doesn’t work for me. has to do with my graphics hardware, i am stick to .18. anyway, if there is need for it and if the axises in .23 are the same as in .18, i can download it and check whether i can edit its loadout like that, too. here is the .18 anyway.

Quarks

Thank you.

Or not so simple after all…
No matter which way I edit the axiseseses… on the Hp, the thrusters always thrust forward with the exhaust effect pointing backward, just like normal. Thrust is also forward regardless of whether the ship is in motion or not.

Also, forward momentum with thrust only is at 1 with a normal thruster.

I placed the Hps on the forward face of the two wings in the bow of the dreadnought. When I hit thrust, I can see the flame effect pushing the ship forward at speed = 1.

1). Am I missing something critical here?
2). Did you have to boost the thrust force of the thruster? I boosted mine from 72000 to 720000 but not seeing any change.

Help?

Why485

As you noticed, the orientation of a thruster has nothing to do with the direction in which the thrust is actually applied. To create my reverse thruster, all I did was apply a negative value to the thrust parameter of the reverse thruster. Doing so causes some minor issues which adoxa pointed out how to fix, but functionally it works as intended.

There was however some bug mentioned earlier related to engine kill. I never tested it myself but it is worth looking into if you plan on seriously implementing this.
