 * =============================================================================
 * Adiciona o sistema de partículas nos sprites dos characters.
 *
 * =============================================================================
 * PLUGIN COMMAND
 * =============================================================================
 * Para ativar o efeito das partículas use esse comando através do Plugin Command.
 *
 * particles_event_id : EVENT_ID : MODE : POWER : BLEND : X : Y : POSITION : FILENAME
 *
 * EVENT_ID = ID do evento do mapa.
 * MODE - Tipo de animação;
 *      0 - Normal
 *      1 - Random
 * BLEND - Tipo de Blend
 *      0 - Normal
 *      1 - Add
 * X - Velocidade da partícula na horizontal.
 * Y - Velocidade do partícula na vertical.
 * POSITION - Posição.
 *           0 - Abaixo.
 *           1 - Centro.
 *           2 - Acima.
 * FILE NAME - Definição do nome do arquivo.
 *      (As imagens devem ser gravadas na pasta /img/charparticles/)
