Hey, I'm wondering how to code something like this:
mob/M in world is M.torch=1
someone uses 'Hougu' verb and M's icon changes to torch.dmi, but only usr can see that, when they click 'Hougu' again M's icon returns.

Could anyone help me?
Thanks for reading.

Look up image in the reference. Adding and removing an image overlay to M is easy. Changing M's icon (the way you want) is a little bit problematic.

soz, but it can be an overlay, it needs to be whole icon

Then you can do something like this:
image
    effects
        torch
            icon='torch.dmi'
mob
    var/tmp/hougu
    verb/Hougu()
        hougu=!hougu
        if(!hougu)
            for(var/image/effects/torch/t in client&&client.images)
                client.images -= t
            return
        for(var/mob/mob)
            if(mob.torch)
                src << new/image/effects/torch(loc=mob) // edit: oops! i forgot..


I didn't test that but I'm pretty sure it works. Modify it in order for it to compliment your game.

It would have better if you checked if the mob has a client - otherwise you will get a runtime if accessing a non-client /mob (ex: NPCs).


Whats with the for(var/mob/mob)? That will loop through all /mob in the world!

If you looked up image(), you can see that a new instance of the said torch is displayed by outputting it to the reference.

It won't cause any runtime errors because I did check if src has a client. If you didn't notice I used the && operator. If client is null, for(var/blahblah in client&&client.images) will be equivalent to for(var/blahblah in null). Otherwise, it will be equivalent to for(var/blahblah in client.images).

I know. The OP didn't say that he wants to see torches only in his view or anything else. Besides, if he wants to, he could modify the code, like what I've told him. If his players are /mob/players, he could change that to /mob/players/mob.

Yea, I forgot to output it. Thanks for mentioning it.
