Colourback problems...

[Nemi]

Er... I'm sort of stuck here... hope any of you could help...

Anyways, I'm doing that 'Snake' game thing as a final project, however, because it's my first year and all, it's pretty much a text version of the game (with a limited knowledge on graphic importation)...

So here's my problem:
I first started the code in Turing 3 and used

code:

var SNAKE :string := chr (157) put SNAKE (1)

to isolate the colourback on just that character.

Next thing you know, my teacher gets Turing 4... and apparently this 'SNAKE (1)' snippet doesn't work anymore -- the colourback continues across the screen regardless of where the snake moves. (Click here for a screenshot)

Is there any way in which I can isolate the colourback on that single character without using a for loop? (I've tried that already and failed miserably.)

NOTE! I'm pretty new at all this, so I'm not that advanced at the coding and stuff...

I would recommend keeping background color the same, and just have a contrasting color of your text instead. I think using '@' character would work best since its round and takes up a lot of area.

Ehhh... more problems...

I've changed the colourback to match with background. Which is good, you can't see the green.

Problem #2:
The 'hidden' colourback erases any 'food' that appears on the right if you move the 'snake' to the left side of the 'food'. (Because the colourback extends to the right end of the screen and erases it) ._.;;

if you dont use colorback at all, the problem shouldn't occur.

Use Draw.FillBox and Draw.FillOval... that would make things simpler too.

Alright... I'll try that out. Thanks!
