I have always enjoyed the petrol mods that come out for gta games. Anything that can add an extra level of realism is good imo.

Anyway, what are the chances of one being created for GTA IV? Once you enter a car it is stored in memory so hopefully it should save the amount of petrol you put in it. This was always a problem with previous petrol mods.

[a-k-t-w]

Yes, I think this is possible. Just make the car stop working after you run out of petrol?

[the_gas]

Yeah i have no idea how to do it, but it would be a great realism mod. If it is made, hopefully the car you are driving will remember how much petrol you have put in it. Thats been the problem with previous petrol mods, as soon as you put the car in the garage, the amount of petrol put in was lost, and you could go from having a full tank to nothing at all.

Another nice addition would be petrol station icons added to the map.

Doing a petrol mod wouldn't be too hard. But it is not possible to store the amount of petrol in the savegame, as far as i know.

[the_gas]

But if you get into a car, and then leave it, that car is stored in memory, ie it stays there unless you quit the game, or get into another car. So there must be some way of getting said car to remember the amount of said petrol.

Yes, this works as long as the current game runs. But as soon as you load a savegame all objects will get new unique IDs and thus the stored information is gone.

it should be possbile by lua-scripting as far as i know. because there is a mod for sa already. and it's a cleo script.

Cant be to hard. Give every car a 'gas amount' and a 'fuel ratio'. Then just read the velocity of the car and do some math. Or am i missing something?

[the_gas]

Good Good, hopefully someone can make it. As long as it remembers my petrol count if i leave my car to say go online, or go to a strip club, then im happy.

[Pandur]

Of course there must also be a way to refill your car at the gas stations!!!
Surely a lot of work, but should be possible!

I hope for it, too!

Hmm could be interesting, I wouldnt even be sure on the maths involved. There isn't any way of drawing to the screen properly yet. So any display that we had last time doesn't work.

^ The problem with this is that it would use up gas whenever you're moving, even if you're only coasting. So it'd be better to have it do the math when W is pressed/the controller trigger is squeezed.

That's a good shout.

Even if you're coasting in a car you're using up fuel. Since the engine is still running and still ticking over.

[the_gas]

True, but but the petrol consumption in this situation must be lower than at top speed, if this can be factored in i doubt it.

[Andrew]

Very true, IV has a velocity varible. I think this holds the amount of acceleration being applied to the car.

I made a very basic mod, my scripting skills arent good, lol. No filling stations yet, or no way to refill the tank, not to mention that one tank is for every car in the game. And it currently drains fuel based on the speed.

Well that's a good start! And yes, sorry, my logic was wrong because I don't know much about the mechanics of cars. I figured only pushing the gas pedal used gas.

[Andrew]

I had a check into the Velocity value, its empty. So that can't be used to drive. I'm going to see if its possible to get a controller press.

Currently the petrol works like so.

-One tank for all cars
-Petrol is drained depending on the speed of the car.
-Amout used goes up in 0.25f increments expect at top speed where its a 2.0f drain
-Fuel is drained every second.

At the present moment, a tank that has 60 fuel, will get you from The Algonquin safehouse to somewhere on the first island. I tried to find a way to turn off the cars engine once you'd ran out of fuel, or set a flag to say can't start car. At the moment I'm having to freeze the cars position and turn on its hazard lights.

Good work Gangsta, sorry i cant be of more help. Hopefully you can continue to improve the mods realism.
