How to structure a game with Irrlicht?

[t]

Hello,
I am wondering how to structure a game using Irrlicht. Let's say the game loop contains these functions

UpdatePlayer()
UpdateMap()
UpdateNPCs()
UpdateDisplay()

Where should they be placed?

The use of callbacks for input etc makes me confused as to where to put things. eg, should I read from the keyboard somehow during UpdatePlayer, or should I respond to a callback event in the callback class?

I would find the source to even a very simple game very helpful.

Hi,
Updates can be conditionned by :
- time
- events
- actions

you don't put updates in the same place together with this theory.

for example :
A timer bomb is linked by time, in this case the periodic update is necessary.

A displacement of player is conditionned by the events of keyboard, periodic update is useless in this case.

That why, i think that irrlicht framework is really good, you have :
- a event receiver function
- a main loop (while(device->run())

It's really important to write your idea on paper, make a diagramm is important too, and check the interaction between class...

bye

Thanks for your reply, cyberbobjr. I think the framework is really good, too.

I wish there were an example showing all these things in a simple game.

I think to publish some code or datagramm, but i don't have some space for putting this... (I'm in work and FTP doesn't be allowed )

You could email me at jjenkin3 then the at symbol, followed by bigpond.net.au
I could also put it on a website for a little while if you'd like.

Hehe... you don't like spamm spider

let me some time to document all and reorganize my code (about 1 weeek or 2) and i'll send you the package
