Scripting System
BlitzMax Forums/BlitzMax Programming/Scripting System

| I'm at a point in my Tile Engine development where I think attaching a scripting system to it would be wise... otherwise, it becomes that much harder to add later... any suggestions? |
| ||
| LUA seems to be the most commonly used. |
| ||
| BriskVM seems popular around the community: http://www.koriolis-fx.com There are also modules floating around for Lua and Squirrel and likely a few others |
| ||
| Or make your own. |
| ||
I was thinking of making my own... it just needs to be able to process stuff like:If I didn't have three kids, a job and a life, I would I'm just not sure where to start with processing the keywords there... Kids, Job... and Life. LOL But seriously... I would rather spend my time making the game not in the weeds |
| ||
| I'm still a fan of BinaryPhoenix's MicroC module, pretty cleanly written, pure BlitzMax, very hackable code. |
| ||
| Seems like Helios site is down.. Can you put up a link to the latest version of MicroC? Also, did it ever go class-based? |
| ||
| lol @ skully LUA is pretty good |
| ||
| Lua is the only option I'd recommend. |
| ||
| How would you use Lua? Ive never used a scripting system in my games, how would you code it to do triggers etc? |
| ||
| There's already a considerable wealth of information on Lua out there, so I would recommend starting with Google. There've also been numerous discussions about it on here, so the search tool for the forums is handy as well. |
| ||
| Although I'm sure BriskVM is a good product, I'd say go with Lua. It's a very easy, fast and powerful language to use, free (although BriskVM is really really cheap), and comes with BlitzMax by default. There's lots of online examples an Lua discussion to be found on the net. They also put the complete copy of the 1st edition of the Blue Pil (Programming in Lua) online. I've got a hardcopy of the 2nd edition and it's a well written book. |
| ||
| Ive looked at Lua, but not sure how to use it to create triggers etc |
| ||
| You'll have to write the interaction layer between Lua and your program yourself. I figure you already have, or should, write a trigger system in your program. Then you just need to export the functionality to Lua so Lua can interact with your program, and vice versa. |
| ||
| write a trigger system in your program LOL... my "trigger system" is: if collideImage[player,x,y,0,key,kx,ky,0] then opendoor[0] etc... hard coded... :( |
| ||
| For what it's worth, trying to fit Lua or any other interpreter into a project mid-way is not likely to be worth it. |
| ||
| It depends on how you designed your program. But it doesn't hurt to keep it in mind whilst designing your program. |
| ||
| In other, shameless pimping news, I just released LuGI, my Lua wrapper generator/core code: http://github.com/nilium/lugi.mod/tree/master It's basically a very small core and a generator. You import the generator, generate glue code, then include the glue code and import the core. There were speed issues with the last one of these things I wrote, since it all depended on the reflection module and resolving everything at runtime, so this is a fair deal faster, since it's all generated and compiled into your project instead. Anyhow, if you decide to look at using it, there are some basic instructions/documentation in the wiki section (top bar, click 'Wiki') on how to use it that I probably can't explain informally. |
| ||
| Thats why I was asking at this point. I'm just created my base actor class and started thinking 'if I don't do this now I'll regret it' I'll definately check that wrapper out...tks! |
| ||
| Htbaa, Lua comes with BMax by default? I don't see any doc references to that. The reason i want to use scripting is because the character in my game will (hopefully) be able to jump into other vehicles/characters etc and there will also be mini-games. I want the mini-games and movement code for the various vehicles to be scripted... the point being that script code can transfer over the net ;) Nilium, I keep seeing references to glew code.. is that the interaction layer between the game and the script code? as in "glewing" the two together? |
| ||
| Yeah in the latest 2 releases of BlitzMax it's available again. I believe with was also available before but somehow disappeared? |
| ||
| I keep seeing references to glew code.. is that the interaction layer between the game and the script code? as in "glewing" the two together? Essentially, glue code is the (generated in this case) code that provides a sort of translation or interop layer between BMax and Lua. Some people write it by hand, some people generate it, etc. I prefer to not write it by hand because that takes ages and there's no much point to doing that with Lua when the interface is pretty much going to look the same for everything (it's also possible to use one glue method for everything, but there are severe speed penalties for that). |
