GameFrame() --> unsafe chagnes question

in my quest for making Spring.CreateUnit() work I was told that I need to incorporate GameFrame() my scirpting in order to keep the "attemtp to make unsafe chagnes" error from showing up
unfortunetly I am haveing ALOT of trouble finding more info on exaclty what I need to do with the GameFrame() function... all I can find is
1) game frame in synced code is called every visual frame -source lua pdf-
2) game frame in unsynced code is called as soon as possible but not neccesarily on the next game frame...-same source-
3) game frame is some how needed to keep from making unsafe chagnes....
this lack of info leads to my first question
question1): does anyone know a fuller guide or source of info that I could refrence to learn more about GameFrame() and what I need it for or can use with it?
in addition to that I am wondering
question2): how can I use gameframe() to allow the creation of a unit Safely?
and finally
question3): do you need the gameframe() to add buttons to units menues? or change resrouces?
thanks for reading :) any info would be great

gadget:GameFrame()
--code goes here
end
1) You need nothing for it. You can use anything with it.
2) Make the unit inside gameframe.
3) No.

aaaa I see
I guess I jumped the gun and thought there was something more too it than that
I dont have one last question though
when I spawn the unit it is un built
how do I make units spawn finished like the commanders at the begginging of a game?

One of the parameters is how far it's built. Make it 1.

hmmm in that case I am deffenetly doing something simple wrong
Probibly I am missinterprieting the spring sites info on this command
here is my code
Code: Select all
function gadget:GetInfo()
return {
name = "CUTests",
desc = "creates units",
author = "zwzsg (and then horribly ruined by Voidranaut)",
date = "not sure",
version = "1.0",
license = "Public Domain",
layer = 0,
enabled = true
}
end
local echo = Spring.Echo
local message_identifier = gadget:GetInfo().name..": "
local once = 1
if (gadgetHandler:IsSyncedCode()) then--SYNCED
function gadget:GameFrame(n)
echo( n )
if( n % 100 == 0 ) then
Spring.CreateUnit( 367, 7110, 45, 2700,(0), 1, 1 )
end
end
else--UNSYNCED
function gadget:KeyPress(key) --key scope exists within the function
if( key == 121 ) then
for _,u in ipairs(Spring.GetAllUnits()) do
Spring.SendLuaRulesMsg(message_identifier..u.." was pressed")
Spring.Echo( u )
end
end
Spring.Echo("Key "..key.." pressed in unsynced")
Spring.SendLuaRulesMsg(message_identifier..key.." was pressed")
end
end
and in this source it says
Spring.CreateUnit note: offmap positions are clamped! (you still can use MoveCtrl todo so)
( string "defName" | number unitDefID,
number x, number y, number z,
(number facing | string "facing"),
number teamID,
boolean build ) -> number unitID
possible values for facing are:
"south" | "s" | 0
"east" | "e" | 1
"north" | "n" | 2
"west" | "w" | 3
if build is true the unit is created in "being built" state, with buildProgress = 0
and because of that I thoguth that the last number at the end of my Spring.CreateUnit() needed to be 1 to have my unit spawn completed... but after trying both one and zero values I have found there to be no diffrence
Question: I am sure I am overlooking something simple. any ideas on were to look or what to reread would be most helpfull thank you

1. Do NOT put a UnitDefID in your file. That can change at any time. Use something like UnitDefNames.armsub.id
2. That's strange that it's not finished. What unit are you trying, in what game?

oh hmmm... I must be supre lucky then because the UnitDefID has been the same unit everytime... the only thing I thought changed radically every game was the UnitID's
oh and I messed up... the document says that a none true value will form a completed unit but of course in my ignorence I assumed they ment 0... I needed to make it nil for it to work.. I forgot about the 0 != flase thing
but ya thanks for pointing me in the right direction lurker :)
hopefuly I can pay give back to the forum communit soon with all you guys have tought me :)

If the mod doesn't change, and you don't flip modoptions that change unitdefs, then the UnitDefIDs won't change either, leading to mysterious breaking code in the future.
