You can do this without the need for any variables at all actually do it like this.

Code:

forward FadeBlood(objectid, alpha, time);
public FadeBlood(objectid, alpha, time)
{
    alpha -= 5;
    if(alpha) {
        SetDynamicObjectMaterial(objectid, 0, -1, "none", "none", 0xFF0000 | (alpha << 24));
        SetTimerEx("FadeBlood", time, false, "iii", objectid, alpha, time);
    }
	else {
        DestroyDynamicObject(objectid);
    }
}
