How can I create water tiles where my bunny can swim? Please help me fast

When you go to set an event, go to Environment->Scenery->Water Level. You can set the Height of the water to what you want there. Anything above 128 makes it possible for players to walk in the water. Setting the height to 0 sets the water level to where the player reaches the event (you're better off not doing this though). You'll have to set "Instant" to 1 (this will instantly move the water to the height specified) so that the water can show up initially. Make sure the player is able to reach the Water Level event, since this is necessary for water to work. And if you want water to show up right as the player starts, you should completely surround your start position(s) with just enough Water Level events.

I suggest looking at Beach2.j2l in JCS if you're still lost (I'm assuming you have this level in your JJ2 folder). You should find the Water Level events are at the top left. And for additional JCS help you may need in the future, here are some links to useful sites: JCSref and How to... JCS.

(someone should probably make an ERE article on this topic or something)

Also, you really wanted the JCS forum, not this one.
