a way to check if plugin exists?

Hi,

I want to know the existence of a plugin. If the plugin doesnt exist, I should create it. My initial thought was by checking

Source code

 
1

if(get(plugin[someplugin]) == null, addplugin(someplugin), removeplugin(someplugin));


but I cant get it to validate. I even tried get(plugin[someplugin].count) == null

Any clues? Atm I resolved it by creating a dummy plugin, so I don't get an error, but it's not the neatest way ofcourse.

maybe this code?

Hi

Source code

 
1

if(plugin[someplugin].loaded, removeplugin(someplugin), addplugin(someplugin));


I use something similar and for me it works great.

Hi,

the 'strict equal' if operater (===) would be also a possibility,

e.g.

Source code

 
1
2

if(plugin[xyz] === null, trace(there is NO plugin named xyz));
if(plugin[xyz] !== null, trace(there is a plugin named xyz));


best regards,
Klaus

I still having problems when I put this in an loop...

if(plugin[get(thumbname)] !== null,
removeplugin(thumbname);
);

sometimes returns ERROR: remove - unknown array item - thumbname

which doesnt make sense, it shoudnt pass the if statement if i couldnt delete it :(

thanks :) I had another error. I tried to removeplugin(thumbname) instead of get(thumbname).

this works:

Source code

 
1
2
3
4

txtadd(thumbname,'thumb_', get(i));
				if(plugin[get(thumbname)].loaded, 
					removeplugin(get(thumbname));
					);


but this too, and i find this better:

Source code

 
1
2
3
4

txtadd(thumbname,'thumb_', get(i));
				if(plugin[get(thumbname)] !== null, 
					removeplugin(get(thumbname));
					);
