i try it i dont know how it works

i am so confused

@name Weapon checker
@inputs RD:ranger Screen:wirelink Screen2:wirelink Reset
@outputs Play
@persist Target:entity Weapons:array Play Allowed:table
if (first()) {
Allowed["weapon_physcannon",number] = 1
Allowed["weapon_physgun",number] = 1
Allowed["gmod_tool",number] = 1
Allowed["gmod_camera",number] = 1
Allowed["gmod_wire_expression",number] = 1
Allowed["laserpointer",number] = 1
Allowed["remotecontroller",number] = 1

Allowed["keys",number] = 1
Allowed["pocket",number] = 1
Allowed["arrest_stick",number] = 1
Allowed["unarrest_stick",number] = 1
Allowed["stunstick",number] = 1

}

interval(20)
if (RD:hit() & clk()) {
Play = 0
if (RD:entity():type() == "player" | Reset) {
Screen[2041] = 1
Screen2[2041] = 1
Target = RD:entity()
findIncludePlayerProps(Target)

findIncludeClass("sent_ball")
findIncludeClass("weapon_*")
findExcludeClass("prop_physics")
findExcludeClass("player")
findInSphere(Target:pos(),25)
Weapons = findToArray()
Name = Target:name():sub(1,20)
Screen:writeString(Name,0,0,49)

for (X = 1,Weapons:count()) {
if (!Allowed[Weapons[X,entity]:type(),number]) {Play = 1, Color = 900} else {Color = 90}
Name = Weapons[X,entity]:type():sub(1,20)
if (X+3 < 17) {Screen:writeString(Name,0,3+X,Color)} else {
Screen2:writeString(Name,0,X-14,Color)
}
}
}
}

if (changed(Play)) {
if (Play) {soundPlay(0,0,"synth/square.wav"), timer("stop",500)} else {soundStop(0)}
}
if (clk("stop")) {Play = 0}

if (Reset & ~Reset) {Play = 0, Target = noentity(), Weapons = array()}

yeah

so it show wat weapons players have
