Using the editor below you will be able to build and share your own Defender levels.
Defender maps have several un-changable properties :
Monsters always move south, there's no going north. You might not have noticed this while playing, but there is currently no way to make monsters travel north, for this reason all maps must be designed using South, East or West. This is simply due to art not existing for North in order to reduce filesize and increase performance.
Waves provided in the editor all default at the same set used for Miner's Cave. So it is entirely possible to build a new map and not touch the waves at all, though I wouldn't recommend it because it'll have no challenge and be pretty boring!
Waypoints are kind of complicated, they are essential to make monsters move due to pathfinding taking up precious performance, there are a couple of rules you must remember when laying them down.
Waypoint 1 is always the entry point for the selected path. Waypoint 20 is always the exit point for the selected path.
Waypoints should be placed at each direction change, generally this will be corners and crossroads. There is some very basic pathfinding that can compensate for sloppy waypoints, but I wouldn't rely on it.
Basically, when placing waypoints, always place waypoint 1 where you want the monster to appear, and waypoint 20 where you want it to escape to, then use 2, 3, 4, 5.. etc. at each each direction change on the path. You don't have to place all 20, but you do need to place them in order, so..
Always "save changes" for the wave you have just edited or you risk losing those changes when you move to another.
Pressing space will clear the current tile from the cursor.
If you think you've come up with a masterpiece and want to share it, you can simply copy and paste the 2 strings created and send them to a friend, they will then be able to play your level exactly as you designed it. (Be sure to playtest it yourself first though!)
