Floating text

-----------------------------------

Is there some way to make text float around the screen?

Have you made a bouncing ball program before?

If so just alter the variables the same way for a Font.Draw procedure, and clear and redaw for effect.

Okay, I'll try that. Thanks for your help!

How do you make the program so that you can add different text but allow them to move at different paces?

Try assigning the word to an array, meaning...

Word is :    Help!

array1 = H
array2 = e
array3 = l
array4 = p
array5 = !

Now that you have the 5 single letters, your free to minipulate each one accordingly and seperatly from the rest.    Or you can go with easier methods, but i dont know those....   Muhahaha math is fun!

No! I'm only in Grade 10 Computer Science, I haven't learned arrays yet...

a) just because you haven't learned something does not mean you can NOT learn it
everything is within ur reach here at compsci.ca here a thought try the turing tuts there they are soo detailed and full of example and then again after you give it a try at it we can help you at it see the glory in this?? 

b) since im soo nice i will give you the link to the array section [url=http://compsci.ca/v3/viewtopic.php?t=14333]here

CChanni do you want to have each character move independently, or together? If they move together, all you need is basic a understanding of collision detection and the Font module.

RE:Floating text

-----------------------------------

You don't need to have an array to select individual characters in a string, because a string is just an array of chars

example 

variable Name has the value "Peter"

lets say we want to output the 2nd letter in the Name var 

var Name : string 

Name := "Peter" 

put Name  (2)

---------

the screen should output the letter "e" 

-----------

This manipulation of strings can also have more than one character selected

put Name (1..5) 

----- 
This will display the first to 5th characters in the var

-----
Also

put Name (1 ..*) % this outputs the first to last char in the string 

-----

hope that helps happy coding

Re: Floating text

-----------------------------------

No one's actually explained what you are supposed to do assuming little previous knowledge so I will.
Have variables holding the x and y coordinates of each letter. have a loop which changes both the x and y by a random amount each time through (look in to Rand.Int). Finally, factor the x and y of each letter into the Draw.Text function for each respective letter. Add in some View.Update and a delay and all have left is to make sure that the letter don't go offscreen.
To do this compare the letters' x and ys with both maxx and maxy (of the screen) and 0. If they are below 0 or above the maxes of the screen, revert them to a position just on the edge of the screen (by adjusting x and y directly). This creates the illusion of a wall.
Always remember to search for information on aspects of programming in Turing help (F10).

Re: Floating text

Below is a post of my program. I think I did everything you said but I'm not sure, so can you check it for me?



View.Set("graphics:max;max;noecho")
var font:int 
font:=Font.New ("MS Reference Sans Serif:11")
var x:= 7
var y:=7 
var xChange, yChange : int := 4
var i: int

loop
x:=y
put Rand.Int (x,y)  
cls
    Draw.Text ("1", x, y, font, red)
    delay (10)
    View.Update
    delay (10)
    x += xChange
    y += yChange
    if x < 8 or x > maxx - 9 then
        xChange := -xChange
    end if
    if y < 8 or y > maxy - 9 then
        yChange := -yChange
        cls
    end if
    end loop
    
    loop
cls
x:=y 
put Rand.Int (x,y)
 
cls
    Draw.Text ("5", x, y, font, red)
    delay (10)
    View.Update
    delay (10)
    x += xChange
    y += yChange
    if x < 8 or x > maxx - 9 then
        xChange := -xChange
    end if
    if y < 8 or y > maxy - 9 then
        yChange := -yChange
        cls
    end if
end loop
