Is it possible to create such skills?

[Murd]

Need help to create skills by using formula box or snippet.

Soul Eater - skill deals damage to one enemy and if the enemy dies by this skill, you gain some HP.

Lightning Strike - hit one selected enemy for some damage then the damage split by half to besides targets (left and right of the selected target). Eg. Slame A, B, C appear. You use Lightning Strike on B for 1,000 damage first then Slame A and C also take 500 damage. If your Lightning Strike hits Slame A or C then only B will take the split damage.

Thanks!

Theoretically everything is possible - but your ideas are a bit tricky.


The first one would require either a lot of complex eventing or a script specifically for it.


The second idea absolutely requires scripting as it would need a different targeting and damage distribution effect.

Check out the battle engine yanfly hosts over at: https://github.com/Archeia/YEARepo . The Lunatic battle stuff in particular can very easily alter skills to do what you want the first one to do, the second requires a bit more work to really accomplish.  I don't know of a battle system off the top of my head that accounts for exact enemy placements.  At best, you'd spread to Enemy A and C regardless of location (EG: one is set up behind the others, it would still get hit by a lunatic multi-enemy attack).

either way, you definitely need some RGSS knowledge to really step into the world of feature ridden skills like that.  Best to Keep it simple if you're not looking to delve into all that complex stuff.

Add this as a new script above main, then in your skill formula put either a.custom_formula_lightningstrike(a, b ) or a.custom_formula_souleater(a, b ). Remember to replace the standard_formula with whatever calculation you're using.

This looks amazing! Need to do some settings for skill damage and try whether the skills work.

Anyway, thank you for your scripts Trihan.

If you have any issues let me know.

Soul Eater - skill deals damage to one enemy and if the enemy dies by this skill, you gain some HP.

You can also try this damage formula with variance set as 0:

dmg = apply_guard(apply_variance(original_damage_formula, var)); dmg = apply_critical(dmg) if b.result.critical; a.hp += some_hp if b.hp - dmg <= 0 && !b.state_resist?(death_state_id); dmgYou may want to try this simpler form instead:

dmg = original_damage_formula * (1 - var + rand(var) * 2) / 2 / b.grd; dmg *= 3 if b.result.critical; a.hp += some_hp if b.hp - dmg <= 0 && !b.state_resist?(death_state_id); dmgUnfortunately, even the simpler form will still likely be too long lol

 

[Trihan]

I don't think that fits in the box and it also won't show a message with the HP gained, though I guess if you're using something like Yanfly's battle engine that's a moot point.

Good point that I didn't factor in enemies immune to the death state, though.
