General / Questions about making tiled game

« on: September 17, 2016, 08:15:25 pm »

Hello. I am making tiled RPG game (all action will be on tiled map with top-down  view). So, questions:
1.How to draw and interact with large map (for example 1024*1024 tiles)
2.How to make mobs and player damagable? I mean how to watch when mob is attacked and when not (should I place this logic inside player, world class or somewhere)?

Feature requests / Add center() method for Sprite

« on: September 14, 2016, 10:17:24 pm »

Hello. Very often I need to center sprite relative to some position. So I have to do something like

sprite.setPosition(newX-sprite.getGlobalBounds().width/2, newY-sprite.getGlobalBounds().height/2)

but it will be very useful to do something this:

sprite.center(newX, newY);
 

Thanks.

General / Implementing spell system

« on: September 10, 2016, 03:45:47 pm »

Hello. I am adding "spell system" in my game. Spells are unique: one just do damage, another moves player in other position, another one adds buff, etc. Can it be implemented in Lua scripting? I mean something like
zeus_arrow.lua in spells folder:

function handler(target)
  --Implemented in C++
  DamageCharacter(target, 20);
end
--Implemented in C++
RegisterSpell("Zeus Arrow", handler);  
 

If yes, then how can I store handler function in C++, and call it everytime when spell is used?

« on: August 11, 2016, 02:51:18 pm »

Hello. I am making a game where player control a bunch of heroes on a field (15*7 squares), and player has to destory enemy's heroes. It will be turn-based game, so hero can walk/attack in 1 turn. What is the best way for designing this game, so heroes will be easily interacted with UI (choose a hero to attack, choose a field square to go) and with in-game logic.
Thanks in advance.

General / Problem with making simple project

« on: May 12, 2016, 03:29:54 pm »

Hello! I found SFML very easy and nice library for games (thanks Laurent), but I just disappointed with it's installation. So I created a simple project (Hello World with Green circle) in CodeBlocks, followed the guide on site, and after run, it started complaining about  something like libgcc_s_sjlj_1.dll was not found.  I moved it to the .exe directory (i used -static-libgcc and -static-libstdc++ flags, but it didn't work). Then it happened with libstdc++6.dll and DW2 dll. Then I ran my .exe, and it said: There is no entry point for _gxx_personality in libstdc++6.dll. I CAN'T even run hello world. Why it is so problematic? Is it my PC's issue or library issue or compiler issue? In VS 2008 Express the same problem (I used VC++ build). Can you explain why it is happening and how can I fix it?

Thanks.
