• Remove need for vector/map casts in known instances
• Fix endless hits on dead bodies in DOOMED
• Remove op/sec limit. It punishes high framerates/logic rates
• Add more/most things to example shim5.json
• Added json_set_*, json_save and booleans to JSON
• Add depth/stencil/cull graphics operations
• Render targets including the backbuffer are now created with depth buffers and stencil buffers

For example if you load the same image twice, the second time it uses the same texture. Same with sprites. So if you run image_update and updates some pixels of one of the images, they all change. There are several ways to get around it, if you want separate images you can _update individually. You can use image_read_texture then image_to_texture to create a new texture. Or image_create then draw the image to the render target.

Sprites are saved in Aseprite as a spritesheet with a json file and tga/png for each separate animation. Name the json and image the same. Now once you have all your animations saved, put them all in a directory together and in that directory create a file called sprite.json:

[ walk_e, walk_w, walk_n, walk_s, throw, jump ]

List all your animations in an array in a json file like above. Now to load a sprite, use the directory name with sprite_load. Make sure to put sprites in data/gfx/sprites.

• Move cfg docs to core docs
• Add casts to make maps in some examples work.

As I previously said, now that types aren’t explicitly set, sometimes you need a cast. Example old code:

map m
= [m "draw"] my_draw

This becomes:

var m
= m (map m)
= [m "draw"] my_draw

BooBooCLI is now free. If you want to distribute BooBoo (game engine) with your game you must buy it on Humble.

• Prioritize command line switches over shim5.json. Make many command line switches available in shim5.json (see devsettings for everything, run with +debug command line switch then press F9 to get devsettings.)
• Add break and continue for for loops
• +adapter command line switch is removed, it never worked with OpenGL
• Changed default samplerate to 48000 Hz as that seems to be the default for quite a while now

• More legible fps/ops/s
• Fix print, string_format and file_print when printing expressions
• Allow an expression to start a container indexing operation
• Added set_blend_mode and constants
• Add ‘limits’ command line switch to shim5.json/devsettings
• Add blend example (seen below)

• font_draw accepts and rtl boolean for RTL text
• Return -1 on fail on load/create funcs
• Move cfg API to standard lib so it can be used by BooBooCLI
