Foi assim que fizemos o gancho encontrado no Mod Obsidian Conflict. O código foi escrito por Hyperjag3 e Skidz. Você pode encontrar uma versão melhorada no YouTube criada pelo usuário MaestroFenix e pode pegar o código do GitHub para testá-lo em seu próprio mod.
Se alguém quiser desmontar isso e escrever alguma documentação sobre como funciona, seria bom. Eu simplesmente não tenho tempo para fazer isso, infelizmente.
A arma foi projetada para multijogador, mas deve funcionar bem em um mod para um jogador, uma vez que você troque as referências a hl2mp. Ele usa o modelo de besta.
NOTA: Se você incluir este código em seu mod de alguma forma, dê créditos à equipe do Obsidian Conflict no arquivo leia-me do seu mod!
Este código foi carregado em 2009, e além de deixar a parte de fazer a versão cliente do código, contém alguns bugs como mover o jogador em todas as direções ou não puxar sempre. No entanto, uma nova versão foi feita:
Substituído o método spring para vetores. Dá maior controle ao jogador em vez de apenas voar em todas as direções. Adicionado um modo de rapel, para que agora os jogadores possam descer/frear sua velocidade de queda com segurança. O gancho agora pode disparar o "gancho" mais rápido (isso poderia ser feito apenas com um viewmodel que possui uma recarga rápida, mas foi corrigido no código). Substituí o parafuso e a corda por uma viga, para deixá-la mais bonita. O “gancho” agora pode ser visto tanto em primeira quanto em terceira pessoa. Antes, pela forma como foi feito, parecia bom em terceira pessoa, mas foi movido no viewmodel. Usa a Arma Gravitacional como modelo. Além de dar créditos à Obsidian Conflict Team, você também deve dar créditos ao Maestro Fénix, que é o criador desta versão melhorada.
Você pode ver um vídeo de demonstração aqui. clique em mim!.
