Sombra No RMXP Com Sprite_Shadow E Sprite_Sun

Sombra No RMXP Com Sprite_Shadow E Sprite_Sun

Achei esse script para o RPG Maker XP bacana, funcional e simples, o Sprite_Shadow.

O script, quando adicionado no projeto permite a criação de uma fonte de luz, que quando inserida em algum mapa, cria sombras no herói (automaticamente) e nos eventos, quando desejado pelo maker. A sombra muda seu ângulo e intensidade, de acordo com a fonte de luz no mapa. Parece que é compativel com o Caterpillar também.

Instruções

Para instalar o script, basta copiar e colar o seu código acima do Main.

Para criar uma fonte de luz num mapa, basta inserir o comentário begin shadow source num script. Você pode personalizar a fonte de luz com os seguintes argumentos em comentários no evento:

  • anglemin n e anglemax n: Substitua n por um número de um ângulo. Os ângulos seguem a grade de coordenadas polares (Polar Coordinate Grid). Se você não sabe o que é isso, eu também não sei, use o Google…
  • distancemax n: Substitua n com o número um para justificar o raio do efeito de sombras. Quanto maior o número, mais longe o actor vai ter sombra.
  • opacity n: Substitua n por um valor de opacidade. 255 fica mais preto preto, e 0 sendo completamente transparente.

Para colocar sombra em algum evento (sem ser o herói), basta colocar o comentário begin shadow. Funciona melhor em chars bípedes, ficando meio esquisito em animais quadrúpedes (sem referências a alguns presentes) e objetos.

Para colocar uma sombra estática, como se fosse um sol, basta você ativar com um script que contenha o comentário begin sun. Note que você precisa de adicionar o código do Sprite_Sun em seu projeto também.

Exemplo

Crie um novo evento no mapa, use um grafico de uma fogueira qualquer e deixe para iniciar em apertar tecla.

Dentro dele adicione um comentário (ou anotação). Ele fica na primeira página da aba de eventos, na primeira coluna, no oitavo lugar de cima para baixo.

Adicione um comentário para cada uma destas instruções: begin shadow source, anglemin 0, anglemax 360 e distancemax 300. Pronto, pode rodar.
