[Begin Action *number of anim*]
Sprite group, sprite number, x offset, y offset, time of sprite.

For example, if you want to do a standing anim (0) with the sprites 0,0; 0,1; and 0,2, with 7 ticks of time each sprite, make this.

[Begin Action 0]
0,0, 0,0, 7
0,1, 0,0, 7
0,2, 0,0, 7

You need to code a HitDef in the state where you char attacks.
Here's a simple HitDef you may use:

[State Hit]
type = HitDef
trigger1 = animelem = 3 (put the # of the sprite in the anim where are the red collision boxes)
attr = S,NA
damage = 20,10 (normal damage, damage when guard)
pausetime = 3,8 (pausetime for player 1, pausetime for player 2)
hitsound = 5,0 (you may increase the 0 to 1, 2, 3, or 4, depending on the attack strenght)
guardsound = 6,0
ground.velocity = -.1,0 (the distance P2 will move horizontal, and vertical)
fall = 0 (change to 1 if the attack shall knock down opponent)

There are lots of tutorials on youtube.
