Simple question about fonts

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


var font1 : int
var fontSize : int
for i : 1 .. 25
    font1 := Font.New ("Arial:fontSize:bold")
    Font.Draw ("Hello", maxx div 2, maxy div 2, font1, red)
    delay (100)
    Font.Draw ("Hello", maxx div 2, maxy div 2, font1, white)
    fontSize := fontSize + 1
end for

Is it possible to replace the size in a Font.New statement with a variable?
any help will be appreciated

Sure it is.  In this case, you've considered 'fontSize' as a string and not a variable.
- "fontSize" vs. fontSize
You'll have to catenate the value of 'fontSize' to the rest of the string.
So, for instance:

var temp : string := "#"
put "a+temp"   %--> a+temp
put "a" + temp %--> a#

See the difference?

- type-casts
Right now, you have fontSize as an int.  To catenate, you have to have all types the same.  You could consider redeclaring fontSize as a string instead, or you could just type-cast it.  E.g.

put 1, " is a number"
put intstr(1) + " is actually a string"

See the difference?  strint() and intstr() are useful, very (simple, acronymical names, too).

Post up your code when you're done so we can see how well you fared.

never seen this before, thanks .But do i put this instr(fontSize)+' outside the font statement. I am getting this error
Bad font size'instr(fontSize)+' in font selection string


var font1 : int
var fontSize : int:=10

for i : 1 .. 10
    
    font1 := Font.New ("Arial:intstr (fontSize)+")
    Font.Draw ("Hello", maxx div 2, maxy div 2, font1, red)
    delay (100)
    Font.Draw ("Hello", maxx div 2, maxy div 2, font1, white)
    fontSize := fontSize + 1
end for



[/code]

you dont put the + after your intstr(fontSize), you  put that before       instr(fontSize), then close the brackets. see if thats wat your prob is

also close the quotes befor your variable otherwise turing wont recognize fontSize as a variable
