Putting variables in the DRAW command.

[Sinuvoid]

How do I do that?? I've tried doing,

Code: Select all

 DRAW "d",a"u",b etc.. 

and I've tried

Code: Select all

 DRAW "D" + a + "U" + b + etc...

Any suggestions on how to do that? If so thanks!

That would work a lot better using strings for variables.

DRAW "U" + A$

Where A$ is a string number. To convert any number to a string use the STR$(number) function:

A$ = STR$(number)

DRAW does not care about spaces so you do not have to trim it.

How do you know that his a and b variables aren't strings already?

[Sinuvoid]

Because they dont include "$" Thanks for noticing anyways

[burger2227]

Because your a JERK Nodvelt! That's why? Why else would Lee's code not work numbnuts?

Go finish your website! It is just another example of your laziness!

Ok, don't go crazy people xD

Bring the paramedics. I think Clippy is having a seizure.

[Nodtveidt]

Code: Select all

DIM A AS STRING
A = "Clippy has fleas"
PRINT A

Type suffixing is evil.

[burger2227]

Most newer programmers do not DIM all of their variables, especially if they are just experimenting. There is absolutely nothing wrong with type suffixes. Look in any book on Basic!

As for the fleas, I must have got them from you! What kind of animal are you anyhow? They are easy to spot on my thin shiny body.

Still no code from Mr B I see. Call me a doctor!

You're a doctor.

That's a pretty gross assumption. You have no idea if a coder, even a "new one", has a background in C, for example, where type suffixes do not exist and are widely considered to be horrible style. Furthermore, I've probably read more books on BASIC than you ever will.

I'm a troll-eating dragon. But I generally use the thin ones like you as toothpicks.

Nice Humor guys

Because they dont include "$" :P Thanks for noticing anyways :)

Uh, did you get your answer, Lee?

As burger2227 implied, you cannot have numbers, just strings.

Demo follows.

Mac

Code: Select all

SCREEN 1
LINE INPUT "Press Enter for demo"; e$
FOR i = 1 TO 10
  DRAW "d" + STR$(INT(RND * 5))
  DRAW "r" + STR$(INT(RND * 5))
  DRAW "u" + STR$(INT(RND * 5))
  DRAW "l" + STR$(INT(RND * 5))
NEXT i

Maybe moderators could remove all posts that does not handle about the topic itself?
Do we have moderators here?

[Sinuvoid]

Yeah I got my answer,but I found a better solution and jsut use LINE. (Im making a library with buttons and text boxes etc.) But im having another problem and its with the COLOR and LOCATE command.

When I type

Code: Select all

CLS
SCREEN 13
LOCATE 2,5
COLOR 15,12
PRINT "Test"

it brings a a popup saying COLOR command stynax wrong or something What I'm I doing wrong?! And also when I use 0 it acts like its transparent...?

[Mac]

im having another problem and its with the COLOR

Unfortunately, each screen has rules about color. It's a pain.

SCREEN 13 only allows one operand. There is no way to change the background without stuff like OUT commands.

Mac

Code: Select all

CLS
SCREEN 13
FOR i = 0 TO 128 STEP 8
  FOR j = 0 TO 7
    COLOR i + j
    PRINT i + j;
  NEXT j
  PRINT
NEXT i
COLOR 7

P.S. As before, don't ask another question. Instead start a new thread for a new topic. You should have made a new thread about COLOR.

[Nodtveidt]

The two-argument form of COLOR doesn't work with SCREEN 13. You can only specify the foreground color.

[Sinuvoid]

Ok, but I think the PALETTE command is going to fix my problem. Thanks! And yeah Ill start a new thread next time

[Nodtveidt]

You can set index 0 to be a different color, but that affects all the pixels of the "background" so that might not be what you want. Ultimately, what you probably would want to do is write your own text function if you want fancy text.

[Sinuvoid]

Function? How is that going to make a differenc form doing it in teh main moduel?

[burger2227]

Even if Lee had the background option, ALL of the background would be changed. However, with 256 color attributes, you can always change parts to other color shades using different attribute numbers.

PRINT will still have the default black attribute 0 behind the text however.

I have an interrupt Function that can change the text background color also.

Do I hear an echo in here or did N just tell you the same thing that Mac already said?
