Game design lessons learned from World of Warcraft – Part 3: PvP and PvE

So I’ll be honest. I’ve had a huge rant building up for some time now on how Blizzard has royally screwed up WoW, and continues to do so, because they have a flawed look at how to balance PvP and PvE gameplay together.

I’m not going to write it because frankly, I’d never want to read it. So I’ve condensed my point into three simple words:

BALANCE

PVP

FIRST

You simply cannot have a PvE game and add PvP on top of it. PvP is player skill, PvE is just numbers. One could go to the extreme and say that they can’t co-exist, but I’m not quite convinced this is true. Close, but not quite.

Adobe Flash 9 & 10 Security Requirements

For those of us messing and working in Flash, the transition from Flash 8 through to Flash 10 have been rife with some major changes in the security model that allows a local Flash application to communicate with the outside world. Adobe, knowing that these are big changes, had its developers write pages, pages, and pages of documentation describing the where what how and why of these updates.

Problem is, it’s very hard to find the simple How-Tos for common situations in all this text. I spent many days scouring and tinkering to figure out the security solution to my application: a flash-based video viewer that would connect into a server and display Motion-JPEG frames that get streamed in.

Hopefully I’ll help save someone else the same hours of research and playing with this problem. My solution is such:

You first need up a simple service on the server you want to connect into that serves the crossdomain.xml content that defines your security policies.

I use a modified version of the service found here: http://www.lightsphere.com/dev/articles/flash_socket_policy.html. It’s updated to be a full Daemon process, so you need Proc::Daemon and Proc::PID::File installed.

Please note:

<site-control permitted-cross-domain-policies=”all”/>

is the required addition to make this script work with Flash 10. Also, if you are worried about corporate firewalls blocking ports < 1000, simply change $port to something bigger, and add the following to your Flash client:

And you're good to go!
