storing original icon so it can be changed back to

I want to create a verb that cheacks my players density and if it is 1 changes the players icon state to a bat and sets their density at 0 , if the players density is 0 ie they are already in bat form it reverts them to their original icon and sets density back to 1.

I have got the verb sorted to check density and convert to bat and i can get it to check the players density and set it back to 1 but how do I get it to restore the original player icon? I assume i need to get it to store it somehow and then revert back?

It's simple. First, store the respective variable (in this case icon) into a backup variable, then use that to restore the variable back to it's previous value afterwards. Unrelated example: 
mob/verb/jump()
   var/old_density = src.density
   src.density = 0
   step(src,src.dir)
   src.density = old_density


You can also use the initial() proc, however note the difference between the two methods (look initial() up).

Well something like this should work:
mob
  verb
    change(mob/M)
      if(M.density)
        M.icon='bat.dmi'
        M.density=0
      else
        M.icon='player.dmi'
        M.density=1

Not sure if the mob/M is even needed. If not, use src.

I have tried what you suggested but it doesn't work, my icon stays as a bat. I have put the code below so that maybe you can see where I am going wrong

            Transform_to_Bat()
                set category = "Powers"     //this code sets the verb to appear in another panel called Powers
                if(usr.power<=0)
                    usr << "You don't have enough power to do this"
                else    
                    var/old_icon = src.icon_state
                    if(usr.density == 1)
                        usr.icon_state = "bat"
                        usr.density = 0
                        
                    else                    
                        usr.icon_state = old_icon
                        usr.density = 1
                    usr.power -= 10

I don't think this will work because in my game you can choose a number of characteristics at login that then determine you icon state so each player will have a different icon state. I need something that will store an indiviual players state and then restore it.

Well you'd have to use a bunch of if statements to get the right icon_state back.

That's almost correct, however, the old_icon variable has to be declared as /mob/var, or it isn't saved between separate calls of the proc. Also, the line old_icon = icon_state must be inside the first if() before you change icon_state to "bat".

mob
  var/old_icon
  verb/transform()
    if(density)
      old_icon = icon_state
      icon_state = "bat"
      density = 0
    else
      icon_state = old_icon
      density = 1


If the old icon_state is only changed once (in your character creation), then you can also just set it there and not have the old_icon = icon_state line at all in the bat verb.

            Transform_to_Bat()
                set category = "Powers"     //this code sets the verb to appear in another panel called Powers
                var/old_icon = icon_state
                if(usr.density == 1)
                    icon_state = "bat"
                    density = 0
                else
                    icon_state = old_icon
                    density = 1
                power -= 10


I tried what you said using the code above but it doesn't work. When i press the button a second time ie to revert from bat form, my icon remains as a bat. Where am i going wrong?

It'll work but I think what you mean is revert to the previous
character with overlays like hair, clothing etc.
I think you can use the flick() proc but I'm pretty new
to BYOND and am not too sure.

Not even close.

The issue is that you didn't follow the advice I wrote.

..Or a variable. Ever heard of them?
