<font style="font-size:125%" color="#55ee99">The UnitDefs[] table holds all information about the units used in the mod.
'''Were you looking for the unitDefs page for Game Developers?''' ([[Gamedev:UnitDefs]])
Note: Its entries are metatables, so you can't use the pairs() iterator on them, use this instead:</font>
 
<font style="font-size:110%" color="lightblue">
==What is this==
The '''UnitDefs[]''' table holds information about the unit'''types''' used in the game. It is indexed by a number, and normally refered to as unitDefID. It is read-only. To access its tags you write, for example,
<pre>
    UnitDefs[unitDefID].name
</pre>
 
'''Note:'''<br>
The name of the keys often vary from the ones in the [[Gamedev:UnitDefs]] files.
For example ''maxDamage'' is named ''health''.
 
==UnitDefs reverse lookup: UnitDefNames==
The '''UnitDefNames[]''' table holds the unitdefs and can be used to get the unitdef table for a known unitname:
<pre>
    local unitDef = UnitDefNames["supertank"]
</pre>
 
==Print all unitDefs==
This example code prints all unitdefs, with all keys and their values (but not their subtables).
<pre>
   for id,unitDef in pairs(UnitDefs) do
   for id,unitDef in pairs(UnitDefs) do
     for name,param in unitDef:pairs() do
     for name,param in unitDef:pairs() do
Line 9: Line 27:
     end
     end
   end
   end
</font>
</pre>
<font style="font-size:125%" color="#55ee99">Very usefull is UnitDefs[i]["customParams"], since you can access any custom fbi param with it and use it in your lua scripts.</font>
Note that unitDef is a metatable, and requires the special iterator unitDef:pairs()
 
==Useful keys/snippets==
<code> UnitDefs[unitDefID].id </code> - gives back the unitDefID
 
<code> UnitDefs[unitDefID].name </code> - the internal unit name
 
<code> UnitDefs[unitDefID].humanName </code> - the displayed unit name


<font style="font-size:125%" color="#55ee99">So because the UnitDefs tables are very large, I simple print here an example of it (BA5.8 core commander):</font>
<code>UnitDefs[unitDefID].weapons</code> - See [[Lua_WeaponDefs]], <code>UnitDefs[unitDefID].weapons[1].weaponDef</code> returns the weaponDefID of the units first weapon, which apppears in the WeaponsDef table as <code>WeaponDefs[weaponDefID]</code>.

==Unit/Weapon damages and armor classes==
 
For details on how to extract which units/weapons target/damage which units, see https://springrts.com/phpbb/viewtopic.php?f=44&t=34382&p=575738#p575738 (TODO: migrate info to wiki).
 
==How to save unitDef tables to file==
To save all unitDefs to a file, including all tables, you can use
<pre>
    local unitDef = UnitDefs[unitDefID]
    local t = {}
    for k,v in unitDef:pairs() do
        t[k] = v
    end
    table.save(t, "lua_unitDef_" .. unitDef.name .. ".lua", "-- generated by table.save")
</pre>
The special iterator is needed because metatables. See https://springrts.com/phpbb/viewtopic.php?f=67&t=33778 for a widget to regenerate the example defs.

Development < Lua Scripting < Lua UnitDefs

Were you looking for the unitDefs page for Game Developers? (Gamedev:UnitDefs)

What is this

The UnitDefs[] table holds information about the unittypes used in the game. It is indexed by a number, and normally refered to as unitDefID. It is read-only. To access its tags you write, for example, 

    UnitDefs[unitDefID].name

Note:
The name of the keys often vary from the ones in the Gamedev:UnitDefs files. For example maxDamage is named health.

UnitDefs reverse lookup: UnitDefNames

The UnitDefNames[] table holds the unitdefs and can be used to get the unitdef table for a known unitname: 

    local unitDef = UnitDefNames["supertank"]

Print all unitDefs

This example code prints all unitdefs, with all keys and their values (but not their subtables). 

  for id,unitDef in pairs(UnitDefs) do
    for name,param in unitDef:pairs() do
      Spring.Echo(name,param)
    end
  end

Note that unitDef is a metatable, and requires the special iterator unitDef:pairs()

Useful keys/snippets

UnitDefs[unitDefID].id - gives back the unitDefID

UnitDefs[unitDefID].name - the internal unit name

UnitDefs[unitDefID].humanName - the displayed unit name

UnitDefs[unitDefID].weapons - See Lua_WeaponDefs, UnitDefs[unitDefID].weapons[1].weaponDef returns the weaponDefID of the units first weapon, which apppears in the WeaponsDef table as WeaponDefs[weaponDefID].

To read custom parameters use: 

    local myCustomParameters = UnitDefs[unitDefID].customParams
    if (myCustomParameters) then
      blub = myCustomParameters.blubfactor
    end

Key-names of the customParams table written must be lowercase and their values can only be strings.

Types of Units

Sometimes one wants to check type of unit. Like is it a factory, is it a transport and so on. Complete list: [1]

  • isTransport
  • isImmobile
  • isBuilding
  • isBuilder
  • isMobileBuilder
  • isStaticBuilder
  • isFactory
  • isExtractor
  • isGroundUnit
  • isAirUnit
  • isStrafingAirUnit
  • isHoveringAirUnit
  • isFighterAirUnit
  • isBomberAirUnit

Unit/Weapon damages and armor classes

For details on how to extract which units/weapons target/damage which units, see https://springrts.com/phpbb/viewtopic.php?f=44&t=34382&p=575738#p575738 (TODO: migrate info to wiki).

How to save unitDef tables to file

To save all unitDefs to a file, including all tables, you can use 

    local unitDef = UnitDefs[unitDefID]
    local t = {}
    for k,v in unitDef:pairs() do
        t[k] = v
    end
    table.save(t, "lua_unitDef_" .. unitDef.name .. ".lua", "-- generated by table.save")

The special iterator is needed because metatables. See https://springrts.com/phpbb/viewtopic.php?f=67&t=33778 for a widget to regenerate the example defs.
