iI have'nt made a new demo in a while , so here you go.

its one way to make a mortar cannon or catapolt with a targeting system and a neat little radar as well(not perfect but
functional and cool anyway) this was made with lite c free , but
published so you can check it out if you dont have lite c.

the enemies dont attack , they just head towards you and let you obliterate them. but hey at least there's something to shoot at.

these codes are free to use no credit is needed.enjoy

mortar cannon demo

very nice ^^

nice!

thanks im glad you like it

Nice, only one thing though, they sometime get stuck to the green circlr, look like you forgot to make it passable

you are right Quadraxas , i geuss because i didnt asingn the
target an action or function of its own i forgot to set its flags
thanks for the bug report.
a new demo has been uploaded with the corrections

Hi!

I try to use you explosion code in my project, but when i shoot and the bullet hits something i get this error: "Dangerous intruction in event big_explosion".

( I copied the smoke, big_explosion, big_burn, and shell_event fuctions directly from you code)

what do I do wrong? how can i solve the problem?

thanks!

you should post your code with the problem

nice demo, but the ents should only show in the radar pic?

here is the code i took from you and my rocket code:
