Animated textures [Zone of Enders]

I have for long wondered how you can make animated textures on a character like in Zone of Enders. For you who have not seen it i have screens from another game called RF online: http://www.mmorpgitalia.it/forum/showthread.php?t=85475

The red lines are like streeks that circle around the cannons texture all the time and "glowing". How would i do this without any specialeffects? I doesnt necesseraly need to glow like an aura but i want to know how animation is possible.

Have a nice christmas holiday people

You could use pixel_to _bitmap, or maybe more simple use different skins. They can be animated simply like this (example from the manual):

action animate
{
while(1)
{
my.skin += time;
if (my.skin > ent_skins(my))
{
my.frame -= ent_skins(my);
}
wait(1);
}
}
