Syntax Error

[ydcl]

Hi all,

I'm currently learning BatariB and have been trying to do a very very simple game. I run into this error when putting player and enemy position: I managed to get the background correct and it runs.

 

2600 Basic compilation completed.

LINE --> missile0y = missile0y - 2 : goto draw_loop

 

I've attached the default.bas file if anyone wants to look at it.

 

Also would love to know how to do a title screen as I have not seen a youtube video on it yet.

 

Thanks,

Yan

That line is not indented

lines 24..26 are not indented either

 

everything (I think) except labels and "end" needs indenting.

Indenting means pressing the space bar once?

Indenting means pressing the space bar once?

Yes, once or more.

 

Also labels and "end" need to not be indented

that is they need to be un-indented

 

Actually, I suppose technically I should say the

first column should be a space while labels and "end"

need to start in the first column.

 

(it could be argued that if everything has a space

and starts in the second column, then technically none

of it is indented or if labels all start in the second column

and everything else in the third column the labels aren't

indented. But it wouldn't compile)

I've been trying to figure out what's wrong with the indentation. I'll read the link tomorrow when I start again. It was working fine until this line gave me problems.

missile0y=missile0y-2: goto draw_loop

that is were the system is telling me the error is.

Here's a working version of your program with everything indented properly and errors fixed and a few adjustments:

 

ydcl_2014y_03m_31d_2216t.bas

 

ydcl_2014y_03m_31d_2216t.bin

[bogax]

This compiles

lines 24..26 have spaces in the names that don't belong.
(fixed here)

Thank you both!

Now I gotta read more into Randoom Terrains how to make the character move.

after some reading I'll try messing with it again for the movement and hopefully a title screen.

[ydcl]

Can someone point me to the exact location for the collision section between missile/enemy and missile player of randomterrain.com? I can move and shoot but I seem to be messing up the collision.

This is the code I have for the collision. the program compiles fine as long as I don't type this in.

 

if collision (missile0,player1)then score = score+1 : player1x = rand / 2 : player1y = 0 : missile0y = 255

if collision (player0,player1)then score = score-1 : player1x = rand / 2 : player1y = 0 : missile0y = 255

It's a good idea to copy and paste any code that you want to modify so it will be harder to introduce errors:

 

randomterrain.com/atari-2600-memories-batari-basic-commands.html#collision

 

You're not supposed to have a space after collision. Instead of "collision (" you should have "collision(".

[ydcl]

Ok, I downloaded one of your collision examples.
