Changing the ammo system?

The "return false" needs to be outside the loop for this to work as you intended. You may also need to manually :destroy() the item when its ammo reaches 0, but I'm not 100% sure.
Autoquark:
Oops! Silly mistake. You were right about having to destroy the ammo item when it ran out, too. That works now, but I have some more questions:
1. I have a missile defined with the MF_RAY flag set, but the game seems to ignore that and still draws a bullet travelling across the screen. It works in console mode however - has the flag become deprecated since graphics were introduced?
2. Is there a list of sprites somewhere? I don't know the names of any of the missile sprites, so I've had to put in random sprites that I do know for now. Although I suppose there is something to be said for a shotgun that shoots shotguns...
3. I've been trying to change the missile property of a weapons using the OnFire hook, but I always get an error when I try to assign it - what should the assignment look like?
4. This is just out of interest, for now: I notice that calling Player:power_backpack() reshuffles the player's ammo stacks. Is there any way to do this without also turning the backpack on? It would be quite a handy feature.

I wouldn't say it is deprecated, just not supported in graphics mode yet.

Alternatively, you could also just copy the values from things you know like beings.imp.sprite.

--- End quote ---
The value needs to be the number id of the missile. Number ids are subject to change between versions, so you should translate from the string id e.g.
--- Code: --- it.missile = missiles.mgun.nid
-- or
it.missile = missiles[string_id].nid
--- End code ---

Honestly, I suspect there are still bugs in power_backpack ;) But no, I'm not aware of any other code that resorts the inventory like this; it is tied together with the backpack flag.
SPTX:
Speaking of sprite. Can I have the source code of the cyberdemon/spidermastermind?
I need to see how a sprite of a size bigger than one tile is handled. When I try to use them, they are cropped from their upper left corner to one tile.

Give a being (or item) the flag F_LARGE to allow for an oversized sprite.
