A question about a spiderman game?

I was playing spiderman the other day (the one based on the second movie) for Play Station 2 and I was having fun. Unfortunately, I then ran into a situation where I needed to use the web powers to swing from building to building, and I don't know how to do that. Basically, how do I shot web?|||i dunno lol|||jump in the air and hold down R2 then follow the directions mate, if you have the problem again u might need to start the game off fresh and read what it tells you.|||Ummm. Its pretty easy. Go to options and controls. Then configure your controls and then change the web control to any key you like. I forgot the default key, sorry!|||IDK you should get a live and stop playing games and go get a girl.
