Spring RTS Engine

hi guys, i was wondering if someone could make a lua script that would turn long range units(like merls, mobile artillery the core missile tank, missile ship etc) hold position, i like to use them for defense or park them next to some place and let them shell.

i would write it myself, but iam a newb when it comes to lua, and theres no way for me to figure out whats wrong with it as theres no error messages, it just doesnt appear in the menu when it doesnt work.

thanks

I'd like to get a Lua script like this aswell, due to the ping I get It usually takes me 3-5 seconds to cycle thru the options to get to hold position, so a script like this will be appreciated.

like i said, ill even write it myself if someone could give me a bit of code that will filter units by they're description, or even name, i would just make a list of all of the long ranged units to affect. unless theres a more efficient way.

Scratch long range units. Make it do that for EVERYTHING. I hate my units suddenly attack a nearby somthing only to get blown up by a dozen HLT's.

Some related widgets to take a look at:
LuaUI/Widgets/unit_stockpiler.lua
LuaUI/Widgets/unit_immobile_builder.lua

ive looked at those, my problem is, i dont know how to check in lua, if a string contains another string, so i could filter descriptions for stuff like rocket, missile, artillery etc, unless i could just do it by range.

Section 5.3 in http://www.lua.org/manual/5.0/manual.html

P.S. I don't really think that filtering by name is the best way
to go. See if you can pick out what you need from the UnitDefs
and WeaponDefs structures (their parameters are listed at the
end of LuaUI/API.txt).

i finnaly got one to work that filters by range, > 300 are set to hold position if they arnt planes and are mobile.

I'd say make that configurable, for various mods/preferences

how does one check if a element exists in a lua table, i was going to make it use one so you could have multiple settings for different mods, with the mod string as the key to the array. once i get that working i was thinking about uploading it.

Eh, if you want to do it for everything, just set your factories to it, that's not difficult, or time consuming.

what i want is only long ranged units to be hold position, my script works, i just wanted to add a way to put different ranges for different mods, but i know nothing of lua so i dont know how to see if a entry with a certain key exists in a table acting as a associative array(std::map in c++, dictionary in python).

Having to set EVERY one of my factories every single game is pretty time consuming. :X And hard to remember.
Automation is win.

I'm sure it would be possible to write a widget that set certain units to hold position, however, I don't have time to write it.

i wrote one, i just need help to make it have multiple settings for different mods, i just need to know how to see if a element with a certain key exists in a lua associative array.

and how do you format strings in lua.

in python it would be
blah = "hello my name is %s iam %d years old"%(name,age)

in c++ it would be.
sprintf(blah,"hello my name is %s iam %d years old",name,age);


and for some reason(i cant exactly get error messages so i have no idea why)

this makes the script not load.

Section 5.3 (string.format)
http://www.lua.org/manual/5.0/manual.html

You can also use the ".." concatenation operator and the
tostring() function (numbers will automatically be converted
to strings when using "..").

example:

any idea why my code doesnt load?

"if(RangeGreaterThen ~= nil)" is missing a then, by the looks of it.
