Hello,

Which is the maximum brushes number supported by Hollywood? May I preload 150 brushes?

Which solution is better:

- preload 150 brushes ?
- preload an IFF picture, cut, and then store 150 brushes in memory ?

It's for tiles game.

Thanks for advance for your advises!

Hello,

As much as your memory can take

May I preload 150 brushes?

Sure.

I'd use the IFF picture and then use DisplayBrushPart() to show the tiles. Then you only need a single brush which saves memory

I've started using displaybruspart () but have a problem with this part of code

Code: Select all

@BRUSH 2,"sprites.iff", {x=0, y=80, width=320, height=48}
@DISPLAY {title="Match-It!", x=#CENTER, y=#CENTER, width=320, 
height=240, color = #GREEN}

text$=UpperStr("u")
posx=0 scry=0

for i=0 to StrLen(text$)-1
a=Asc(MidStr(text$,i,1))-64
Print (a,"")

Switch a
Case 1
    scry=0
    Case 2
        a=a-20
        scry=17
EndSwitch

DisplayBrushPart (2,(a-1)*16,scry,posx,50,16,16)
posx=posx+16
Next

Repeat
WaitEvent
Forever  

In fact, values from 0 to 20 for "a" are for letters A to T Value 21 and more are for letters U to Z But my code is not working. It's only working if I use no switch command and use only letters from A to T

Can you help me?

Thanks!

If I remember correctly the "Switch-EndSwitch" commands works only with constants, you can't use

Switch myvar

if myvar is a variable

Thanks for your help. I've tried this way but did not success too

Code: Select all

text$=UpperStr("test u")
posx=0 scry=0

for i=0 to StrLen(text$)-1
a=Asc(MidStr(text$,i,1))-64
Print (a,"")

if a>20 scry=16 a=a-19 Else scry=0

DisplayBrushPart (2,(a-1)*16,scry,posx,50,16,16)
posx=posx+16
Next

Repeat
WaitEvent
Forever      

Error is "next without for"

Any idea?

Bye

Eric

Hello Tarzin!! The solution is very simple: you have tested the string "test u" but the space has asc code = 32 so subtracting 64 from this code you have a negative value that break your script. I've tested with the string "testu" (removing the space) and all runs fine. You have to parse the string checking for special character with asc code < 64, for example if you encounter a space you can simply increase the current posx, and so on. Hope to have resolved you problem!!

Good coding! Fabio

P.S.: Here is your original code corrected (a Next was missing):

Code: Select all

@BRUSH 2,"sprites.iff", {x=0, y=80, width=320, height=48}
@DISPLAY {title="Match-It!", x=#CENTER, y=#CENTER, width=320,
height=240, color = #GREEN}

text$ = UpperStr("testu") ; <-- Space has asc code = 32 so here you have
a
                            ;     negative value which cause and error!
I've removed
                            ;     the space for simplicity.
posx  = 0
scry  = 0

For i = 0 To StrLen(text$)-1
    a = Asc(MidStr(text$, i, 1)) - 64
    DebugPrint (a, "")

    If a>20
       scry = 16
       a    = a - 19
    Else
       scry = 0
    EndIf

    DisplayBrushPart(2,(a-1)*16,scry,posx,50,16,16)
    posx = posx + 16
Next

Repeat
     WaitEvent
Forever

Nope, that's definitely not true. It wouldn't make much sense if you couldn't use Switch() with variables

Thanks a lot for yout help, all run fine now! I'll try to adapt all my original Amos code to Hollywood. That's "the difficulty". My part of the game is done but in Amos.

See you soon with my next problem!

My faulty memory!!

<Switch variable> is allowed but not <Case variable>, that's right?

Exactly

Case can only handle constants!
