Hello.
How can make a bridge system
where when the player walks on ground he can pass under it
and when go up the hill {for example} can pass on it and that occured on the same map
I built a Demo for a script a while ago that explains in the Demo how to do this.
http://www.775.net/~heretic/downloads/rmxp/cat.php
The Demo itself is for a Caterpillar / Message System Script, but also contains a ton of information on Advanced Mapping Techniques. There are no enemies in the Demo. So just wander around until you get to the Cave. One of the Characters in the cave will explain, in detail, how to accomplish a Bridge System. It is a bit of work, but not as difficult as you would think.
Thanks on your replay.
but unfortunately I have a problem with Internet speed and cannot download the demo.
Anyway I expelled using this system in my project ,otherwise I be necesserated and found a way myself
