Minor issue with icon states.

[LordShekelstein]

So, I'm working on a clown-based martial arts which involves the firing of a "honkdouken" projectile. I've gotten the spell code to work, however, icon_state is giving me some difficulties.

First and foremost, here is what I'm working with.

The problem I've been getting is that the spell icon button thingy appears invisible as does the projectile itself as seen here:

Here is where I have the icons stored.

I'm not to sure why this isn't working to be quite frank. Any assistance given would be very helpful.

Have you set the icon_icon value properly for the button? Same for the projectile, ensure that the icon variable is set properly
Also, your button_icon_state doesn't have a 0 or such after it while your icon_state in the DMI does

Yes I see the issue. Since you're copying from the fireball spell, what you should do instead is make the honkdouken spell a subtype of fireball spell, with fireball_type = obj/item/projectile/magic/honkdouken so it fires your honkdouken projectile.

[LordShekelstein]

Right, so I took a bit of a break because this was frustrating me a tad. However, I've done as you suggested and made it a subtype of fireball. However, it is now saying that fireball_type is undefined. Any fixes?

[SteelSlayer]

You haven't made it a subtype yet.
The path of the fireball spells is: /obj/effect/proc_holder/spell/targeted/click/fireball
And so your spell should be: /obj/effect/proc_holder/spell/targeted/click/fireball/honkdouken

This also means you do not need the honkdouken cast proc at all, since its the same as fireball, and will be inherited from it. And then of course, you can remove the var/ from var/fireball_type in your spell definition.

Edit: Also I forgot you'll need to change this line from:
var/obj/item/projectile/magic/fireball/FB = new fireball_type(user.loc) to
var/obj/item/projectile/magic/FB = new fireball_type(user.loc)
Inside the fireball's cast proc. since your houkdouken projectile is not going to be subtype of fireball.

[LordShekelstein]

So, I think I've done it properly. However, it still isn't showing the actual projectile. As an aside: apologies for making you type out the word "honkdouken" so much.

At this point I don't know whats wrong without having the code. I suggest using the debugger, and stepping through the code to see what the issue is.

Didn't you and I fix this @LordShekelstein ? If I recall, you had not defined where the sprite file was for your icon, adding that (so it didn't inherit the wrong file location) fixed the issue.
