2D Water in GameMaker: Studio 1.4

This easy-to-implement feature-engine, to use in GameMaker: Studio, lets you implement water in your 2D platformer with responding waves!

The water can be customized easily in multiple ways, and the code is well documented, to make it easy to both use and tweak.

To use this feature you simply need to add the included water object and sprite to you project. Resize the water body in the room editor, to fill out the area you need to be water.

This engine can easily be used with both my platformer engines (https://gumroad.com/l/simpleplatformer, https://gumroad.com/l/platformer), but can just as easily be used with your own projects.

Update: Version 2
Now the engine has precise collisions, and generally optimized code + an unique boolean accessor variable 'is_water_surface_collision' to use in collisions with the water, to tell if you are in the surface or not!

The old version is of course still accessible as well.
