Adding skateboard

I dont think so its possible. Never seen it on any samp server.
Tschüss ihr kacklappen
It is possible to be added as an item/object attached to your skin if that's what you mean, no more than that.
That's what I said, it can be scripted as an object/item attached to your skin(specifically the character's hand). Other than that it's a feature which isn't possible to be added as Mike is not a samp developer.
There is no use of adding this as a clothing item  🙁. I just thought it would be cool if players had something to travel faster like this instead of jumping all around.And at the same time it could be used to attack players too (imagine dying from a skateboard xD)
Thanks for informing Latz
Not possible and even if it were it would be so abusable...
