Super Cool! Thank you a lot.

Here is my code based on yours:

PHP Code:

new const Float: Multi[] = {

    1.0,      // HIT_GENERIC
    4.0,      // HIT_HEAD
    1.0,      // HIT_CHEST
    1.25,     // HIT_STOMACH
    1.0,      // HIT_LEFTARM
    1.0,      // HIT_RIGHTARM
    0.75,     // HIT_LEFTLEG
    0.75,      // HIT_RIGHTLEG
    0.0      // HIT_SHIELD
}
