Advanced Landmine, Expression 2

[singilli]

[ame="http://www.youtube.com/watch?v=zysvYraOZfw"]YouTube - Enginn's tutorial #2 - Advanced landmine (E2)[/ame]

Now includes ChatMine at bottom as requested.

Whenever you pick up the prop the e2 was spawned on it will not explode, when it comes to a stop it will arm that part of the explosive again.

Advanced Landmine:

Part 1 - Building the contraption

1. First spawn a PHX 1x1 plate, freeze it.

2. Place a wired "Button" onto the plate toggled with Value on: 1 and Value off: 0, it is under Wire - I/O.

3. Place an "Explosive" and make sure the trigger value is at 1 other options are up to you, it is under Wire - Physics.


Part 2 - The expression 2

[highlight=e2]@name Advanced Landmine
@inputs Button
@outputs Detonate
@persist Plate:vector True

#Whenever you update the Epression it won't explode
if (first()) {Plate=entity()os()}
#Makes it run every game tick or 10 milliseconds, this way it won't be affected by lag
runOnTick(1)

#If player holds the entity the Expression is welded to the explosive can't explode
if (entity():isWeldedTo():isPlayerHolding()) {True=0}

#Gets the position of the expression as a vector
Plate=entity()os()
#If True equal 0 and the plate has stopped moving True is set to 1 again and that part of the explosive gets armed
if (True==0&$Plate==vec(0,0,0)) {True=1}
#If the delta of the plate is not 0/if it has moved, the button is 1 and True is 1 Detonate is 1 else Detonate is 0
if ($Plate&Button&True) {Detonate=1}
#Self explanatory
else {Detonate=0}
[/highlight]

Copy and paste the code and place the expression

Part 3 - Wiring it all up


1. Wire the "Button" input of the expression to the "Button".

2. Wire the Explosives "Detonate" to the "Detonate" output of the expression.

Part 4 - Better understanding of the expression used


Line 1:
[highlight=e2]if (first()) {Plate=entity()os()}[/highlight]
If it's the first run of the expression it will get the vector position of the Plate so it doesn't blow it when you update it.

Line 2:
[highlight=e2]runOnTick(1)[/highlight]
Makes it run every 10 millisecond.


Line 3:
[highlight=e2]if (entity():isWeldedTo():isPlayerHolding()) {True=0}[/highlight]
If you hold the entity the expression is welded to with the physgun, it will make the variable True equal to 0. If True is 0 the explosive can't explode.


Line 4:
[highlight=e2]Plate=entity()os()[/highlight]
Updates the position of the expression


Line 5:
[highlight=e2]if (True==0&$Plate==vec(0,0,0)) {True=1}[/highlight]
If the variable True is equal to 0 and the Delta of the vector of the plate is 0/the Plate variable is not moving. It makes the True variable 1 and thus arming that part of the bomb.


Line 6:
[highlight=e2]if ($Plate&Button&True) {Detonate=1}[/highlight]
If the Delta of the expression is changing/the expresion is moving and the Button is equal to 1 and True is equal to 1 Detonate = 1.


Line 7:
[highlight=e2]else {Detonate=0}[/highlight]
If one of the variables at line 6 is not equal to 1, Detonate is equal to 0.

ChatMine:

Part 1 - Building the contraption

1. First spawn a PHX 1x1 plate, freeze it.

2. Place an "Explosive" and make sure the trigger value is at 1 other options are up to you, it is under Wire - Physics.


Part 2 - The expression 2

[highlight=e2]@name Chatmine
@inputs Button
@outputs Detonate
@persist Plate:vector True ChatActivate

#Whenever you update the Epression it won't explode
if (first()) {Plate=entity()os()}
#Makes it run every game tick or 10 milliseconds, this way it won't be affected by lag
runOnTick(1)

#Saves the last thing the owner said as the variable Arg
Arg=owner():lastSaid()
#If you say /act it will activate the mine
if (Arg=="/act") {Chat=1}
#Else if you say /deact it will deactivate the mine
elseif (Arg=="/deact") {Chat=0}

#If player holds the entity the Expression is welded to the explosive can't explode
if (entity():isWeldedTo():isPlayerHolding()) {True=0}

#Gets the position of the expression as a vector
Plate=entity()os()
#If True equal 0 and the plate has stopped moving True is set to 1 again and the explosive gets armed
if (True==0&$Plate==vec(0,0,0)) {True=1}
#If the delta of the plate is not 0/if it has moved, the button is 1 and True is 1 Detonate is 1 else Detonate is 0
if ($Plate&Chat&True) {Detonate=1}
#Self explanatory
else {Detonate=0}[/highlight]

Copy and paste the code and place the expression


Part 3 - Wiring it up

1. Wire the Explosives "Detonate" to the "Detonate" output of the expression.


Part 4 - Better understanding of the expression used

Line 1 (changed):
[highlight=e2]Arg=owner():lastSaid()[/highlight]
Makes the variable Arg become the last thing you said and is saved as a string.


Line 2 (changed):
[highlight=e2]if (Arg=="/act") {Chat=1}[/highlight]
If the variable Arg is equal to that you said "/act" Chat is equal to 1.


Line 3 (changed):
[highlight=e2]elseif (Arg=="/deact") {Chat=0}[/highlight]
Else if the variable Arg is equal to "/deact" Chat is equal to 0.

Do note that I just threw this code in and it's very inefficient, ask for help if you want to know how to make it more efficient.

[Wizard of Ass]

Instead of the button you could use a chatController... and why you don't apply the phx plate model to the explosive?

[singilli]

I know, I'm going into chat controllers later on. And what is the second thing you are talking about?

[B0B]

You should change the model of the e2 (wire_expression2_model [modelpath]) or the model of the explosive so that you don't need an extra prop.

And please don't use chat commands... or everyone will know if you activate the mine.

But anyway: Nice Landmine I like the idea to be able to pick it up

[Lyinginbedmon]

You could use a chat command to arm it though, and then perhaps E:aimEntity() and E:keyUse() to deactivate it.

[B0B]

Why want everyone to use chat commands? they are ******* ****.
I suggest to do it like Lying said but activate it with it too and use hints for status.

[Lyinginbedmon]

Using chat commands however would allow them to activate them all simultaneously. Using my idea for both activation and deactivation would be very time consuming when laying a field of mines.

Someone asked for code with chatcommands. Here it is. That is nothing special it doesn't include any super hard commands just your very basic Chatmine as I like to call it.
