Oh, yes, I think it was an odvious step, but I will add that step, to avoid any confusion. Thanks for the results on the doc, happy to hear it works properly.
About the bow and fire weapons and axe (bow and axe are both melee weapons, managed by the same system), they can be adjusted by their respective melee tool or the IK weapon tool.
You can skip the part of the creation of the melee weapon, but it shows the melee weapon adjustment.
And here for fire weapons:
About the arrow, it can be also adjusted, it is better explained in the FAQ section of discord, I have planned to add that whole section on the main online doc, as I am going to add more content to that doc along bringing new tutorial videos.
I can post the bow adjustment here later
About the input, not sure what you mean, do you mean to turn off inputs or categories of inputs on GKC?
If you mean that, yes, it uses a custom input system, very similar to the one of new unity input, as it allows to create and configure new actions without any code, setting the 3 types of inputs, gamepad, keyboard and touch and their respective key assigned and the type of press (hold, release, or down) and the event that triggers for it.
You can see more on the doc and you can rebind the default keys or disable any of the actions or category of actions on the main input manager component on the player parent or the player input manager for that player on specific.
Let me know more details about what you need, no rush.
Regards.
