[Kexanone]

When merged this pull request will:

• Rename ODIN_SkillEditorAttribute to ODIN_GroupSkillEditorAttribute
• Add a character skill attribute
• Add global skill attribute

Looks good!
Is the skill setting for SCR_AICombatComponentan int while for AIConfigComponenta float? I assume arbitrary scale vs. percentage?

[Kexanone]

AIConfigComponent's skill is not an arbitrary scale. It's a float value from 0 to 1. Group prefabs have a slider for that.

[Kexanone]

And SCR_AICombatComponent's skill is enumerated, but accepts any integer. 100 is enumerated to CYLON, which is likely the highest setting.

[Crowdedlight]

As talked about on discord, the skill-setting for the enum is used in prefabs as combo-box and not a slider. So values between enums might not be handled properly. (good spot!)

So lets change that setting to combo-box too.

enum EAISkill
{
    NONE,
    ROOKIE    = 20,
    REGULAR    = 50,
    VETERAN    = 70,
    EXPERT     = 80,
    CYLON      = 100
};

Also adding global settings as discussed.

I kinda forgot about this. Is it still WIP, or ready ?

[Kexanone]

Still WIP. I doubt skill is functional for the current AI, so there's no point in completing it at the moment.
