Implementing Spell Cast Time

[dkun]

What I'd like to do is to add cast time to spells and be able to specify with each spell how many turns each takes to cast.

I can't seem to find any plugin that does this other than Victor Engine's Charge Action plugin. I've tried using it but it doesn't seem to be compatible with Yanfly Battle Engine Core. When I tried using it, while the casting state is applied, the skill is immediately used (and the character essentially double casts, casting the spell again after the cast duration). I turned YEP Battle Engine Core off temporarily and it worked normally. However I don't really want to turn it off.

I'm not sure if this can be implemented with simply the use of default functionality. I've had the idea of using YEP Buffs & States Core and use the Custom Leave Effect to the 'Casting' state to force the character to cast the spell but I realised that I had to know how to specify the spell used and would need to possibly have two skill entries for one spell.

I would really appreciate suggestions as to how to do this.
