here are the answers to ur queries:

1. u are using the educational team edition, changing of window title is only available in the Pro edition. this function is not required for an educational project.

2. as EvilSOB mentioned.

3. preferably via code instead of skills.


few clarifications: Are u using C-Script or Lite-C ? lite c file extensions are .c

for setting physics params and passable etc. its good to do it in code, more flexible,
