Lua: Metatable OOP

Lua has long been hailed as a very flexible language that allows programmers to create features they need from it even if those features do not exist by default. One such notable feature is an object-oriented paradigm that can be implemented in Lua using metatable manipulations. By request of friends, this post will give some basic insight into how this is done. Continue reading Lua: Metatable OOP

Useful CS2D Lua Functions: Part II

Recently, I’ve been asked twice about how to check if there’s something obstructing the path from (x1;y1) to (x2;y2). Here I’ll provide two implementations equally useful – to check if there’s something obstructing the way for a player (wall or obstale) and to check if there’s something obstructing the way for a bullet (wall).

Useful CS2D Lua Functions: Part I

So, this post will begin a series of posts that provide some useful CS2D Lua functions and explain how to use them. The functions provided are some very popular ones, people constantly ask for them, so this series of posts will allow them to refer to ready code chunks without annoying people on the forums.

A very popular request both in personal messaging and on the forums is, “How do I find the position of an object if it continues to go where it’s facing for X pixels?” Paraphrased, of course, but that’s what people ask, one way or another.

Custom Weapons

So I had this nice idea a while ago about making a custom weapons script, but at the time I lacked the skill and the knowledge. Now I took on that project again, and it turned out to be pretty nice actually. Right now I’m working on visual effects and the ammunition system – it’s going to be displayed with real number sprites from CS2D. Quite cool, quite cool indeed. The progress so far can be seen here.
