As of 1.2.2 we changed almost every visible chat message. So like 90% of JX Mod is translateable.
HUD messages (like cures and heals aswell as round end stats) are not really translateable due to them only allow ascii characters.
In the translation file make sure that your text is always surrounded by 2 ". Example: "Message here"
Note you will see a line saying "#format" "{1:d},{2:s}" or similar versions do not translate these lines as they are used to tell sourcemod what to replace.
Either remove that line or keep it.
the {1} and {2} etc will be replaced by either names or numbers {green} will replace the text behind it green and {default} is the normal yellowish chat color
"CannotHeal"
{
"#format" "{1:s}"
"en" "Medic {green}{1}{default} can no longer {green}Heal{default}!"
}Filled with variables this will look like Medic Joux can no longer Heal ! where the {1} will be replaced with the medics name in this example Joux
Another note: if you see %% this is not a typo %% will in the end give %. This is the way the function works which translates the text. (To keep it simple)
Once you are done with the translation (note this is alot to translate) just add it again to an archieve and use the forum attachment function to upload it or send it via PM to either Joux or me and tell us which language you translated jxmod to
