gdextension-uBASIC-Godot

gdextension uBASIC-Godot

a first picture:

yet another example for gdextension. imho i think theres still not enough documentation for gdextension.
im interested in interpreters and i found Adam Dunkels uBASIC. a cool oldschool basicinterpreter.
i inject uBASIC with gdextension to godot as a node. programmed in c++ for windows, tested with 4.3.dev4.
the basic-program test.bas produces the output you see in the pic:

5 print "hello world from uBASIC-Godot"
10 gosub 100
20 for i = 1 to 3
30 print i;
40 next i
45 print "3*2+4="
46 print 3*2+4
48 setcolor 0 0 255
49 setwidth 3
52 drawline 50 50 450 250
48 setcolor 0 255 0
49 setwidth 6
52 drawline 20 500 600 20
54 setcolor 255 0 0
56 setwidth 12
58 drawline 20 250 600 250
80 print "end"
90 end
100 print "subroutine"
110 return;

godot-specific-commands:

godot-specific-commands, i extended (look basictest/test.bas exampleprogram).

drawing lines:
setwidth number - set the linewidth for example 1
setcolor number number number - set the drawcolor for examle blue 0 0 255
drawline number number number number - draw a line from startx, starty to endx, endy

usage:

with the dll in bin, godot should know the new node, you can find if you search for UBASICGODOT.
Godot generates also a helppage.
in inspector select the UBASICGODOT-node and type in the name of the basic-program.
in this test it is test.bas
you can write own programs with texteditor of your choice.

build:

for build, you have to insert godot-cpp, follow the gdextension-example in godot-docs
if you build it for example for linux you have to expand some files like UBASICGODOT.gdextension...
