Monster Throwing

[ian_scho]

Hi again,

I have an event that a monster will throw a dagger, for example.

Here is a snipped of my dummy code, the bit that isn't working. As you can see I have hard coded the direction and tile position for test purposes.

Code: Select all

		local throw_power = 38
		local damage = 30
		local delta = 8           
		dsb_shoot(id, level, x, y, NORTH, NORTHEAST, throw_power, damage, delta)
		dsb_set_openshot(id)
		local_sound(mon_id, snd.swish)

Thanks!

What doesn't work?

From looking at that code the main problem I see is that you're not defining the variable id anywhere. For dsb_shoot to work properly you need to have something to shoot. So, if you haven't created the dagger, you'd have to do so beforehand.

Code: Select all

local id = dsb_spawn("dagger", LIMBO, 0, 0, 0)

Otherwise, I'd need more information to get to the cause of the error, because that code looks fine...

Ohhh thanks for that. I think you pointed me in the right direction there.

It was probably to do with id's where I passed an instance to a function, which called dsb_swap(what, "flask"), but I suspect I still had an 'old' reference in the parent function... My ignorance of LUA? Passing parameters by reference, value or by memory reference!

Will play some more

Numbrers are passed by value, and everything else (strings, tables, bitmaps, etc.) are passed by reference.

OK, thank you. I destroyed the old and created a new instance as shown in your example, which works now.
