Hi everyone!

I'm working on a mod for new heroes and I would like to know if it's possible to create a new faction skilltrees instead of using one already made. 

I checked the forums but wasn't able to find anything.

I found that in the file "HeroDefinitions" you can assign 3 SkillTrees but haven't found how they are made.

So please if you have any information I would gladly hear it! :)

With some additionnal researchs I found out that you need the files "HeroSkillTreeDefinitions" "HeroSkillDefinitions" and "SimulationDescriptors[HeroSkill]" So I'll leave it here in case someone need help with that, but I'm still wondering if there will be issues with the "race" of the hero and the faction logo in the skilltree. I'll need some more tests for that!

Exactly what I was looking for, thank you!

I know I'm resurrecting an old thread, but it's the only one I've found that deals with customising (modding) hereos. So if any can help I'd appreciate it.

There is a warning in the ...\HeroSkillDefinitions.xml that says     

"<!--
    -   Note: be careful with alternatives, as the skills get replaced only in the skill tree, not in the hero unlocked skills set.
    -   That means that if you set a prerequisite that checks dynamic properties, you can unlock the skill and then its alternative once the context has changed,
    -   because it will not change the unlocked skill, only the skills showed in the skill tree
    -->"

In the ...\SimulationDescription[HeroSkill].xml file there are referenecs to Level 0, 1, 2, 3, 4 which not all skill sets have and they don't always start at 0. 

Also there's a section called "<!-- FEEDBACK FOR SCAN VIEW -->" which I'm not sure what it's referring to or how it works. Once again not every skill set seems to have this section of code.

Has anyone got a clue what these do and how to modify a hero skills without breaking the game?

If you are having an issue with modding it’s best to upload the mod (here or in #modding) so we can have a look and see if we can spot any issues (much quicker than trying to guess)

(If there still are in the game) there are two features of skill trees that are not used in vanilla, Required skills (i.e. Skill X needs Skill Y to be selected before it can, even draws a line between them) & Alternative skills (i.e. Skill A is shown be default but is hidden and replaced with Skill B if the prerequisites set are met) The warning for them is that if you have a prerequisite that can change in game (e.g. the hero level is >10) then if the hero had skill A before it got hidden it will skill have the effects of it when it does get hidden.

@CyRob, Thank you and I'm grateful for any guidance.

I'll do my best to get a mod together soon, even though I'm still struggeling with understanding how the whole xml file linking to other xml files work. Like how does "HeroTerrans01" become "Dimitri Lenko" in the game? So far I haven't found how or where that happens in the xml.

It seems that there are quite a number of files that need to be tied together to make the mod work, including GUI and Tooltips. Any pointers on where all the Hero based files are, that make it all tie together, would be much appreciated :)

I would suggest at the Example Hero mod but in general everything is split up in the XML, the names are stored in localization files which a GUI file points at, heroes & skills are in different files and thier effects are in simulation files.
