# Test scripts

The Lua scripts used to verify the 3D scene and physics work, one per stage
of PLAN.md sections 18 and 19, with everything they load:  the Khronos
Duck, Fox and BoxAnimated sample models under Models/, and Box.png.  The
disc and the font are the engine's own, addressed as
Singe/menuBackground.mkv and Singe/FreeSansBold.ttf like any engine
asset.  This directory is a complete Singe game directory.  Run one from the singe directory with

    .builddir/Singe-v3.00-Linux-x86_64 -w -d data -v Singe/menuBackground.mkv testScripts/scene6.singe

or pack it (singe --pack testScripts testScripts.game) and run an entry
with --entry N (the numbers follow games.dat).  Every script takes a
screenshot or two and quits by itself; the results are in screenshots/.
