Random Encounters!

[Wormopolis]

Browsers Tested: IE, FF and Chrome
placement: board footer and global footer

This code allows you to setup a one-click button that generates a random encounter from a list of monsters you create. you can define all of the monster stats, min/max appearing, how rare the monster is, and even some custom attributes for that monster alone. you can also define if the monster would appear with other monsters and how many!

have a look at the example troll to see how a monster is edited. I would advise to keep that default one in there for later. it wont affect you results.

the global footer part comes with some default CSS you can edit for how the encounter tables look.

[norunubbc]

[killz4food]

What is the footer supposed to do? I've placed it in the global but it doesn't seem to do anything? Can I get some insight?

[Wormopolis]

the board footer is to allow the click button to show up and setup the data.

the global footer just converts any tags it sees to the tables

[killz4food]

I dont see anything in the designated board footer having to do with a button? Did I do something wrong?

[Wormopolis]

when you reply to a post or create a new thread, you should see a button.

[Wormopolis]

otherwise I need to see how you edited the array

Thats exactly how I have it in. Along with the gloabal one

[Wormopolis]

I would leave that first troll alone. it serves as a template for adding monsters and now that you have edited it will mess up future monsters because it was done wrong. it is commented out so it doesnt affect the code. but the one monster you added does. and it has some editing mistakes


encounterList[Griever]={
Frequency: '8',
Min: '5',
Max: '10',
Stats: [['Strength','3','20'],['Agility','1','16'],['Hit Points','10','30']],
Weapons: [['Saw arm', 60%','(20-40)'],[Three finger claw','75%','(15-25)'],['Mace','50%','(30-50)']['Prodding Arm','100%','(5-15)'],100%],
Spells: [],
};


Griever needs to be in quotes
the 60% for saw arm needs to have a quote before it
missing comma between mace and prodding arm arrays
the final "100%" in the weapons array will cause an error because it doesnt match with any of the weapons

[Wormopolis]

you also cant just delete variables you dont like. you will cause the code to stop because of that

[killz4food]

aww. I see. And what do you mean the %100 has to equal the weapons array?

[Wormopolis]

in the weapons array, you basically have an array of arrays. think of it like this:

Weapons: [
['Saw arm', 60%','(20-40)'],
[Three finger claw','75%','(15-25)'],
['Mace','50%','(30-50)'],
['Prodding Arm','100%','(5-15)'],
100%
]

see how the "100%" at the end doesnt look like the other lines?

[killz4food]

Yeah. So should I make it a sort of stat then?

[Wormopolis]

what is it for? what are you trying say there is a 100% chance of?

[Streamstrider]

I love this idea! However, my forum doesn't exactly use a stat system, so I'm going to ask if there's a different way of doing this. XD

Instead of Stats under the encounterList, could it just be a short description of the creature encountered? Or even just a statement? (Basically, just optional text.)

For Weapons, could there simply be an array of a possible weapon and a short description?

Spells can be omitted or changed to "Magical Properties"?

Company doesn't need changes, I don't think.

Possible?
