[beta 20b] Crash when a worm cast gravity well

[Marcotte]

Hard crash, as the game seg fault. (beta 20b, self-compiled, on linux 64 bits)

Here is the end of the log:

I left out a targeting check.

1079 in damage types should be.

Code: Select all

-- Gravity damage
newDamageType{
	name = "gravity", type = "GRAVITY",
	projector = function(src, x, y, type, dam)
		DamageType:get(DamageType.PHYSICAL).projector(src, x, y, DamageType.PHYSICAL, dam)
		local target = game.level.map(x, y, Map.ACTOR)
		if target then
			if target:checkHit(src:combatSpellpower(), target:combatPhysicalResist(), 0, 95, 20) and target:canBe("pin") then
				target:setEffect(target.EFF_PINNED, 2, {}, true)
			else
				game.logSeen(target, "%s resists!", target.name:capitalize())
			end
		end
	end,
}

DG I'll send this in a patch probably later today. It didn't crash the release copy (or at least didn't when I tested though it did produce a lot of errors).

*edit* Patch sent.
