Start of a silly Galaga style game - Marcus - 11-07-2024

Yep, 'draw image xform' is pretty new, so you better download the latest version
Nice to see you here

Could you please advice me ?

RE: Start of a silly Galaga style game - kevin - 12-02-2024
Hi, I have not had a chance to look at your code, but I think a similar problem was discussed here:
https://www.naalaa.com/forum/thread-138.html?highlight=Return
Hope this helps.
Apologies if I have misunderstood the problem.
All the best.. Kevin.

Thank you for your response, Kevin. I'll learn the code at the provided link above.
Meanwhile, just another simple silly game is in progress ....
Code:

' ALIENS TOOK MY COWS (updated)
' Aliens are coming...
' They are abducting your cows.
' Now, they challenge you,everytime they tell you ...
' a number of alien's spaceship, find out its
' coordinate and they'll return your cow one by one
' ... Good luck !

Well... I am totally confused... (not 'that' hard to do actually... lol)
Am I supposed to enter the co-ordinate of the alien listed or guess the co-ordinate of the listed alien? If it is "guess" then my chances are quite remote... 3 attempts... Try #1 is 1 in 45, #2 is 1 on 44 and #3 is 1 in 43... which works out to a 1 in 85,140... mind you, it's WAY less than the lottery... lol or am I over-thinking this... lol

Co-ordinate based game, it isn't good for aliens (Galaga) ... lol .....
I'm thinking to recreate "Whack-a-mole" or you may call it as "Marsupial Mole".... I don't know if it is the same as "Wombat" ?
RE: Start of a silly Galaga style game - johnno56 - 12-03-2024
