Projectile shooting script request

[Zack The Great]

I Request The Following: :thumb: Its for a Gauntlet-like game for RPG maker XP.

Projectile shooting script:
for
RMXP
Detailed Description:
I wish for this script to work in the following ways:
-When "D" is pressed...
A graphic [Being the projectile] will appear that will show an arrow, magical orb, throwing knife, bullet, or axe, depending on the character.
-When the Graphic hits an enemy, the enemy will execute the common even I have made that will send the monster back until it is recalled by its originating spawner [aka fortification], unless that fortification is destroyed, then the monster will not respawn.
-If the projectile hits the wall, the projectile will vanish

I want it to work kind-of like it does in Gauntlet II (Arcade), when you press the shoot button, all of the above ways I want this script to work is executed.

Text example
p= player
*=executes
r= projectile
E=enemy
W=wall
> V < ^ = projectile paths

example 1:
w
P*r>>>>>>>>>> E w
w
If
^
^
E
or
E
V
V
before r>E
then:
E w
R>w (result: projectile is destroyed)
w

but if

r>E (enemy gets hit)

Then R>E (result: projectile is destroyed and enemy being destroyed executes the proper common event)
