How about posting a small .bas file that has the set up, playfield, and a main loop. Then somebody can download it and play around with the playfield.

[Erik Zimmermann]

No problem. It's for a board game.
a) 2 players, 2 missiles and balls
b) 8x8 fields
c) player jumps between fields.
am a beginner really need help

 

what's wrong with the missiles? Not same y pos.

If I remember correctly, the missiles and ball never line up right with the sprites. You have to play around with the numbers.

 

I could turn that into a DPC+ version so it looks better if you want (unless you need the extra variables that superchip gives us). You could have something like 44 rows or 88 rows instead of only 32 rows. The row lines would also be gone when using DPC+. You could also use sprites for everything instead of the missiles.

Hello,

 

Thanks. Yes. It is very nice.

I have the checker board on the screen and player0 moving correctly.

 

Now I have some questions:

 

Question 1

Is the player only supposed to move in one of 4 directions or do you want diagonal movement too? With a board like that, I'm assuming you want the sprites only moving up or down or left or right and not in combination. For example, if the player is moving down, they won't be able to move right or left until they stop moving down.

 

 

Question 2

This is related to question one. I'm assuming you only want up/down and left/right shooting. No diagonal shooting. Is that correct?

 

 

Question 3

Is the other sprite supposed to be controlled by another player or the computer?

[Erik Zimmermann]

This is a 1-2 player game.

Humans control the players.

The computer controls the player.

Players can fire. The missile moves where there is no obstacle.
The missile always follows the enemy.

A ball moves across the map.
If the missile hits the ball, blocks are placed there.

If the player collides with the playfield, he cannot progress.
If the missile collides with the Playfield, it ricochets off. (flies back)
The missile collides with the ball. Blocks are created.
If the missile collides with player then dead.

Rules from Checker and other board games can still be incorporated later.

OK, I got you started out.

 

Here's the .bas file:

calpos_dpc_2022y_02m_09d_1447t.bas

 

 

Here's the .bin file to use with your favorite emulator:

calpos_dpc_2022y_02m_09d_1447t.bin

 

 

Sounds like you want a lot of things in your game. I'm working on my own game when I can find the time and trying to find a house and packing boxes for the move (we have to be out of here by April), so I don't have time to do that much work on a game for somebody else right now.
