Damaging fish with grenades

[Plasticizer]

Hi,

I'm creating a mod & depending on the entity that has been killed, you'll get a different item.
But when trying to damage the fish with anything but a bullet, it doesn't seem to work.
i.e. rockets just delete the fish, any other explosive or capsule does nothing, ...

How can I make the fish take damage from the grenade that hit it?

I tried collision damage like bullets, but that doesn't seem the case.
Also, I've noticed "fire" does damage the fish as well...
So it doesn't seem to be "under water".

Any help is welcome

what I've tried to add to the grenade, but it does nothing

Code: Select all

		table.insert(
				action.action_delivery.target_effects, 
				{
					type = "damage",
					damage = {
						type = "capture", amount = 100 * strength
					}
				}
			)
			table.insert(
				action.action_delivery.target_effects,
				{
					type = "activate-impact",
					deliver_category = "bullet"
				}
			)
			table.insert(
				action.action_delivery.target_effects,
				{
					type = "create-entity",
					entity_name = "explosion-hit",
					offsets = {{0, 1}},
					offset_deviation = {{-0.5, -0.5}, {0.5, 0.5}}
				}
			)
			table.insert(
				action.action_delivery.target_effects,
				{
					type = "invoke-tile-trigger",
					repeat_count = 1
				}
			)
