Blender Game Python Scripting Tutorials' title='Blender Game Python Scripting Tutorials' />Lua Versus Python. Introduction. Python 1 is a popular programming language. Both Python and Lua are commonly embedded in applications to provide scripting support. Scripting is more frequently being used in games. There are many factors to take into account when choosing a scripting language. It may be a simple decision based on the architecture of the target platform like whether you are on a PC or game console. Assuming you have the luxury of a fast CPU, virtual memory, and hard disk storage, the vast library resources of Python could help get your project completed sooner. If you dont have those luxuries, Python is not an option as it is quite large. General Comparison. The following is a simple comparison, with advantages of both Python and Lua over each other listed. Python Is better equipped. Huge library of very useful functionality. Very useful for off line work, e. Huge catalog of example scripts 2, tutorials 3, help 4 and general reference material 5. Extremely high performance numeric computing ala scientific and graphics is possible with an add on module that implements true multidimensional arrays. Strictly speaking, Lua has no arrays and must use a table structure for them. Lua arrays are tables, thats true. The implementation has dual nature, however, and array usage 1. N indices is optimized as it should be. Also, its not really true that Lua must use a table for arrays. Its possible to create optimized arrays like the ones you describe with userdata. Blue Pi. L of this. Python 2. 4 and scheduled for core inclusion in 2. Best Website Unblocker Software. Blender Game Python Scripting For BeginnersC wrapper. See Alien for this functionality in Lua. Has a remote debugger 7. See list of remote debuggers for Lua 8 Lua has a simpler though more minimalistic syntax and could not have been made much simpler. The difference is not huge though. Compare 91. 0. Python has extensive slicing for strings and lists, which is a big productivity gain. I would recommend a slicing library be used by those who want to be more productive in Lua. Python has more extensive though by no means perfect Unicode support. Python is whitespace sensitive. Experienced Python developers know that this isnt an issue once the point of this feels weird is gone. Besides not being a problem, it collaborates to standardizing the way code looks, thus facilitating the readability across different code bases. FUD about this being a problem is usually spread by people not using it in a daily basis, as some sampling in Google can easily demonstrate. A pretty printer exists for Lua, so code could be standardized just as easily as for Python. Shark. DYeah, but youre not forced to use it. Python forces your code to look at least half way decent. Big difference. MR. Python has binary operators or, and, xor,. Embedded systems really benefit from these, though Lua can be extended to include these with addon libraries or using Lua. X enumerations. Lua 5. Howard. Harkness Python has the ability to reduce errors though somewhat more static type checking. Lua programs are much more error prone, due to automatic coercion, accessing of unset variables without an exception, and having to check most functions for nil values, rather than just catching the exceptions. There may be some advantages to some of these points however. IMO the only decent way of solving this is static analysis. Most of my catastrophic globals typos have been in less used codepaths, and even had w survived, they would have blown up on people at the worst times. Hence Lua. Lint, which I suppose I should have a go at for 5. Jay. Carlson. This is an issue of strongerweaker1. Blender Game Python Scripting Basics' title='Blender Game Python Scripting Basics' />Python has much more beginner documentation. There is still a lack of introductory material for Lua. Lua Smaller footprint than Python. Look at the size of python. A basic Lua engine, including parsercompilerinterpreter, but excluding standard libraries, weighs in at under 1. Seems to lack any use or implementation of pointers, References. What about USERDATA and light USERDATAAll tables are passed by reference. Faster interpreter Lua vs. Python and faster JIT compiler Lua. JIT vs. Psyco 1. Has a nice simple API for talking between script and C, with very little generation of glue code required. Try creating and manipulating lists and dictionaries in Python and then doing it in Lua. Doesnt use reference counting for objects which can get complex and error prone. Although you can use things like the Python Boost library 1. C. Lua started off as a configuration language. This has some nice quirks in that its great for creating and configuring things which is what you want to do in a game. Blender Game Python Scripting For Arcgis' title='Blender Game Python Scripting For Arcgis' />Has a nice, simple, and very powerful syntax. I find you can write the same thing in Lua with less code than Python and you have more flexibilty because of Luas metamechanisms. Lua although you can make them behave like Python.

Zero to Hero Game Developer Bundle Leap Into A New Game Development Career Through 83 Hours of Training In IndustryStandard Tools Tech. Lists and Python. Dictionaries. Anonymous functions are also particularly nice for configuring things. In Python you get their poor cousin, lambda functions. Small, simple, stable codebase. Adobe Acrobat 9 Pro Crack Key Downloads. Easy to poke around inside and modify if need be. Probably not as well documented and commented as Python. Its really not that easy to poke around. And there really arent that many comments. I disagree. I found it refreshingly simple to poke around in the Lua sources and make changes to the compiler and VM. The codebase is very clean and well thought out. Few external modules make Lua easier to bundle for a specialized purpose, even if the vanilla build has less functionality than required. Compare this with pythons numerous modules which include libraries that come with the standard distribution. Lua does support multiple threading. Multiple Lua intrepreters can exist in the same process and each one can run independently in its own thread. Thus Lua is more suitable for embedding in multithreaded programs. Lua is not whitespace sensitive. Manual De Test Benton Y Luria. While this has its downsides when compared with Python, there is no need to worry about automatic editor space to tab conversion or vice versa. When using a proportional width font, Lua allows use of as much indentation as necessary to make the code easy to read. Lua has out of the box support for multiple threads and multiple interpreters in a single thread or process. Python does not support multiple threads with multiple interpreters in a single process. Multiple threads can access the Python interpreter but each thread must hold a global lock while doing so. This is incorrect. The global interpreter lock GIL is per interpreter as its name implies, not per process you could indeed embed multiple interpreters in a single process. Jonathan. Ellis The original author is correct, the GIL is per process. You can have multiple interpreters, but theyre just a scoping thing, they do not allow multiple concurrent threads to run. See 1. 9 for the most concise discussion Ive found on this. But original author is still wrong in the statement Python does not support multiple threads with multiple interpreters in a single process, depending on how you want to interpret it. The GIL is per process. You can have multiple interpreters. You can also have multiple threads. These can be running in the same or different sub interpreters within the one process at the same time. When any one specific thread is running in Python code though it will acquire the GIL, in doing this you lock out any other threads which need to have the GIL at that time when running.
