The coding for the rocket is found here:
There is a con file and tweak file. You can add the code to the tweak file. Just open the tweak file in notemad, use find to find the first instance of an addTemplate entry and just drop your code there.
Well yes I would like to consider my self smart. But really BFheroes is just a upgraded BF1942 engine. Sorta like 3rd generation after BF1942. Upgrade of BF2142 engine which is an upgrade of the BF2 engine which is also a upgrade of the original Refractor 2 engine BF1942 runs off of.
So a lot of the coding in BFheroes is done in the same way as BF1942, so much of my BF1942 modding knowledge also applies to BFHeroes.
Expect BFheroes to be the last of the Refractor 2 engine based BF games. BFBC2, BF1943, and the future BF3 game will all use the new FrostBite engine, so it looks like the good ol' Refractor 2 engine is going way of the dinosaur.
However on the bright side, they might release some source code for BF1942/BFV. I want to revive the lensflares, skidmark system, and the weather system and it looks like it will take some game engine changes to turn that stuff back on.
Remember. BF1942 infact started out as "Rally Sport Challenge" or something rather. It's a racing game and predates Bf1942 by a few months! It uses Refractor 2 game engine and is the first example. I downloaded the game and looked at the code and it is VERY similer to BF1942. A lot of the object classes from BF1942 exist in this game and even the coding structure is similer. Funny to think that BF series started out as a racing game. :P
(note that the Refractor 1 engine which is many times older is used by an old game called "Codename Eagle". It's really old and I don't think it's coded the same. So I haven't bothered to look at that one. Though I do recall someone ported that to BF1942 in a mod somewhere. :P )
