Use
; Jump = 1,Q,A,zero,P,enter,space
; Shoot = 2,W,S,Z,9,O,L,period

Ship moves and launches bomb that create craters. You can shoot the ship.
If you don't jump a crater, you get returned to BASIC.

Comments Welcome...

Looks good! Are you likely to open the source? Benefits are that you can get constructive criticism from the community. Disadvantages are that the community keeps making constructive critiques :lol:

Sirmorris,
I will post the source after I get a little further along. It's kind of a mess right now as I am just "making it work".

Actually what the heck, here it is...

Bean

P.S. What I could use is some help with the graphics, I'm not an artistic person...

The graphics look fine to me. Are you interested in getting more designs? I think in 2x2 characters you can do a few good ones.

I've done some rudimentary UDGs for this but the problem I'm having is that the same CHR$ are used for the sky, moon surface and part of the Vehicle so creating a UDG for one makes the others look odd. likewise part of the crater is also using the same CHR as the vertical firing missile so after the bomb drops the crater consists of a bit of space plus missile.

Unfortunately as its self running I can't get at the graphics and an ASM listing might as well be in Greek as my simple grasp of all things assembler is virtually nil. :oops:

The only way a simpleton like myself could convert this is for the moon buggy,missiles and the crater to be built up of different-not used-elsewhere CHR$ no matter how ridiculous it may look at first before converting.

The wheels are ok and I think I've managed a nice movement effect.

I believe Z'pand has a STOP feature if you own one. There are other POKE codes to stop mentioned in this forum though I can't find it right off hand.

Found it...

Moggy,
I will make the characters different so the UDG can work better.
I'll use inverse periods for the top section, etc...

What about making the sky inverse space (maybe with occasional inverse period), the ground (white) as regular space, and the mountain halftone graphic, and the car and bullet half character grey halftone, half black to match mountain?
