Create your own UObjects : generally these are .cc files, see tutorial: UObject documentation for more details.

How to compile:

Template exists for Visual C++, Dev-CPP, see Gostai Website for downloads

Manual method: create a Makefile file with this in it:

#name of the final binary
PRG=myBioloidEngine

#where is the folder named "urbiengine-bioloid"
URBIENGINE_BIOLOID_DIR=/

LIBURBIENGINE_BIOLOID=\
$(URBIENGINE_BIOLOID_DIR)/usr/local/gostai/core/i686-pc-linux-gnu/\
engine/liburbiengine-bioloid.a

BIN_BIOLOID=$(URBIENGINE_BIOLOID_DIR)/usr/local/bin


all:
	$(BIN_BIOLOID)/umake-engine --prefix=../usr/local \
	-o $(PRG)   $(LIBURBIENGINE_BIOLOID) *.cc

clean:
	rm -rf _ubuild-$(PRG)  $(PRG)

$PRG is the name of the final binary you generate.

$URBIENGINE_BIOLOID_DIR is the install directory where can be found .../gostai/core/.../liburbiengine-bioloid.a.

To compile your engine, just enter make in a shell in your directory.
