Nice and easy.
Would look better with GUI contribution when about invitation with accept/decline and score

The system now has a GUI, Thanks for your suggestion .

That's just awesome! That's how a duel system should look like, in vcmp 0.4

[Gulk2]

I'll use it but mod it, to give the gui vice city style. Nice job

Woow, irony? xd, Thanks anyway

I'll use it but mod it, to give the gui vice city style. Nice job

What style would that be?
I will gladly change it, but I need an example of the gui what you want.

This font is the official one used in VC for subtitles,
https://fonts2u.com/sf-arborcrest-heavy.font
VC contains other fonts too.

what if sender decide to cancel their request? i think you forgot about it?!

[Maximiliano]

what if sender decide to cancel their request? i think you forgot about it?!

I think you haven't seen the video, the system has to accept and deny duels. '-'

[Saiyan Attack]

i have seen it and i have also seen your command /duel cancel - that can use only for those user who sent request of duel ... and i want to tell you about when sender cancel their duel request and then the popup window should remove automatically ....
