Help with Animation

[Zurc]

So, I've been working on my game, but I noticed that my animations are wrong. I'm just new to MMF2 and I need help with my animation.

You see, When I press Z, my character attacks. It destroys opponents, but the problem is animation.
Same with walking. When I hold the Right/Left button, it does the animation, but only once and it just stays there if I stop.
Please teach me how to do walking and melee animations.

(The Melee animation is another object, just relevant to the position of the player by 32/-40, position is modified by the direction of player)

It's a 2D Sidescroller Action game, similar to NG Trilogy.

In the animation editor you can set the walking animation to loop. If you're using standard movement, no coding are needed for the walking animations to work.
The melee animation should be easy. Simply execute the attack animation when the player presses Z. Make sure the default animation is set to loop so that it will go back to play that animation automatically after finishing the attack animation.

If you're still stuck, don't hesitate to ask more questions

NOTE: My melee object is active.
I set it to disappear after certain time by using alterable values.

This is the complete description:

I set the melee object's direction by holding the right/left key.
Upon pressing Z - Change animation sequence to attack =this is what I did.=
Without loop, it only does the animation ONCE.
But when I go to animation editor, then edit the melee active to loop, the active continues to loop when I press Z (even though it's already invisible.)

EDIT: Nevermind, I kinda fixed it by adding a stopped animation, so when it goes visible, I set the animation back to stopped. Then when I press Z, it changes to attack.
