Here would be a perfect time for you to make a full project or tutorial yourself
, plenty of people will give you advice if desired.
1st step, create a design doc
http://www.runawaystudios.com/articles/chris_taylor_gdd.asp <-- every time i do a project, i usually start from this template.
Make sure you've got every detail of what you want in it! that includes units, buildings, how much power they should have etc..
next step
compile a list of things to do with your game. What are the core components, then you can worry about making it look shiny and polished after you've finished the core parts to the game.
e.g. simple list:
HUD - with building menu
Terrain
be able to place building / check for places cannot be placed
do check if enough money
reduce money when baught
place building
update building in your array / database for that player
be able to click/highlight buildings
select building to do x task
building to make unit
texture unit with correct image
unit clickable/highlighted, so you can move them
The most boring part of this will be the database part, storing all the units information and building information in a nicely accessible database / (array) / struct
The Database information:
It's up to you what to decide to put in here. For example for ease of use, what i did for my first RTS was compiled a list of attributes for troopers / tanks etc.. it would have an array like this
Power[troopers][level] = 10;
Health[troopers][level] = 1000;
Speed[troopers][level] = 2.2;
Power[tank][level]=40;
Health[tank][level]=2000;
... and so on
The troopers/tank = an enum previously set, the level is depending on what level you want to set your troop to have these stats, in my game they were able to go up to level 5.
I'd love to create a full tutorial right now but I've got a compiler to write and I must get back to work. If you require any help you can always post what part you're stuck in, but just give it a try
. If you don't believe you're experienced enough yet i suggest building a tower defense game with the use of stats for each building etc.. that will give you the necessary experience without the project being too big. Estimated time for tower defense (1 month)
