If you are into creating digital games, you must have heard of or know about Roblox. It has grown rapidly as a popular online gaming platform where users can create and share games. Roblox is not a game but a customizable platform where users can connect to the Roblox Studio to create amazing games and virtual worlds.
One of the outstanding characteristics of this platform is its exclusive use of the programming language called Lua. This scripting language lets you create simple to complex gameplay mechanics, interactive atmospheres, and a lot more cool features.
Today, we will be sharing five key techniques you need to know. Whether you are running a game development company or just having fun, these tips will help you get the best from your adventure.
About Lua
Lua is one of the most popular scripting languages in the world. It supports procedural, functional, object-oriented, and data-oriented programming. In most cases, it’s not used as a standalone language; rather, it’s integrated with other programming languages, mostly C and C++. However, when it comes to game development, it can easily stand on its own and make incredible virtual presentations.
The popularity of Lua is mostly in this area. Any game development service should know about it because it’s used largely in the developer community. It has several advantages that encourage faster and easier development of games.
It’s estimated that Lua will have a market share of about 8% by 2021 and be the fourth most popular programming language globally. Today, it holds a higher rank, especially as game developers keep increasing.
5 Lua Techniques You Need To Know
If you decide to develop your next big game, like World of Warcraft and Warframe on Roblox, you must know Lua is a scripting language. And it’s not just about knowing how to use it but also getting the best from its open-source code. We have five tips here that will help in that major project you are working on.
1. Follow the Rules of Program Optimization
Often, we have seen developers get too excited when it comes to working on their big projects. This can easily distract you and cause you to make costly mistakes. Lua, just like any other programming language, requires the user to always follow the main rules of optimizing a program.
Rule #1 says, “Don’t do it, ” while the second rule (for experts) says “Don’t do it yet.” They may sound out of the norm but, you will find these maxims especially crucial when using Lua, a programming language popular for its performance.
A respectable game development studio will tell you Lua deserves its reputation among scripting languages. However, they will also tell you that performance is a key factor in proper programming. You should know this from the beginning because a result that is too late will not help you at all.
2. Use ‘Locals’
Lua has relied on a register-based virtual machine since version five. You may have noticed that these ‘registers’ are not the same as those registered on the CPU. Any correspondence would not be portable, and it would mean having fewer of them.
In Lua, a stack accommodates more registers, giving you up to 250 registers for each active function from an activation record. Because of this large number, Lua uses registers for all local variables, making access to local variables easier in this programming language.
3. Using _G to Discover Translator API
Lua presents everything in the form of tables. Usually, you may not need to know how tables are implemented when you want to use them. The details don’t even show up to the users. However, it might be necessary to understand them through the table operations performance.
Underscore G is a table, but in the global environment, it includes every EPI in the Lua functions. This makes it easy to access all the Lua libraries.
4. Understand Strings
You must understand the implementation of strings to use them efficiently. Unlike most scripting languages, Lua strings are internalized (it keeps a copy of any string). Also, the valuables in Lua don’t hold any strings. It only references, which speeds up the manipulation of different strings.
This could result in low operations in the concatenation of certain strings. Lua does not offer any faster option, so you must apply an explicit butter. Using a table with the string pieces will make things faster. Also, you can join strings faster using the ‘..’ operation.
5. Reduce the Need for New Objects
Every game development company or individual wants to use as few objects as possible when working on any project. In Lua, you can use the three R’s used in conserving our environment: reduce, reuse, and recycle.
For example, if you have a program with many tables, you can manipulate the polylines to change its date representation. You change records into arrangements instead of normal list points. This will save up some space. Also, you can reduce the need for new strings by applying indices on the created strings, and when you must create new objects, try reusing the strings as much as possible. The best way to reuse is through memorizing, where you store the results of some computation into a specific input, which prompts reuse whenever necessary.
Conclusion
Roblox has certainly gained traction across the globe with its unique setup and interactive gaming model. It’s largely beneficial for those who want to create and publish games for free. However, it requires some knowledge of its programming language.
We hope the five techniques we have discussed above will set you on the right path. It’s all about understanding Lua to improve its performance and work faster.
