SnapMap Custom Module Bounds Shape

Define snap module bounds using custom shapes. This opens up lots of possibilities for snap map based dungeons. Previously the doors had to be aligned at the edges of the axis-aligned bounding box. Now you can place the doors at any orientation, at the edge of your custom polygon shape and create a more tightly packed and organic looking level

We’ll look at setting up custom bounds shapes (like boxes, cylinders or polygon) in your module level file

Open up a snap module that you designed

Drop in a Snap Map Module Bounds actor on to the scene. You can have as many of these actors as you like in the module to cover the bounds


Circle Shape

By default, it’s set to a polygon. Lets change it to a circle

Move the bounds accordingly.

Grab the radius handle and adjust the radius

Adjust the height with the height handle

Box Shape

Add another bounds and set the shape to Box this time. Adjust it so it aligns on one of the door opening

Do the same of the other 2 doors

IMPORTANT: After you modify the bounds, it’s important that you rebuild the Module database cache

Polygon Shape

Use the polygon shape to wrap your dungeon bounds using a polygon. The polygon should not self intersect. If it does, the system will ignore the bounds, since the shape is invalid and the bounds would not be shown

It would show a a dashed border like this:

You can provide a concave polygon and DA will automateically split it into several convex shapes (so collision check is faster)

Final Notes

You don’t have to go very agressive with this, just have a general bounds that cover everything and it might be ok to leave out some small stuff. The goal of these bounds is to make sure other modules do not overlap with whatever is inside this. Try to not have too many of these shapes as it would increase the time required to check for collision
