different way to use sprites in PlayBASIC from DarkBASIC

[Laskiapina]

I'm just migrating from DarkBASIC and having trouble adjusting. What I'm trying to do is cut a sprite from picture and use it as the player image.

PlayBASIC Code: [Select]

loadimage "sprites.png",1
getimage 1,490,1,560,55

drawimage 1,x,y,0

sync

So could someone just tell me how to use sprites in PlayBasic the simple way?  ::)

PlayBASIC Code: [Select]

loadimage "sprites.png",1

rendertoimage 1

getimage 2,490,1,560,55

rendertoscreen

drawimage 2,x,y,0

sync

Ah, I see. The first image is #1 so you have to start cutting the sprites from #2. And if I got it right, you have to tell the program what it must work on - on the picture data or on the screen. Thank you. Moving on. :)
I was making a platformer on DarkBASIC when I noticed that DB doesn't meet my requirements. So now I'm changing the code to work in PB.

Are images slower than sprites? Is it wise to use DRAWIMAGE for drawing platforms and other stuff (a lot of them) or does the program get too slow?

Apparently I can't use collision detection if I use only DRAWIMAGE. I read the image tutorial, but it didn't help me much. So how am I to change the images to sprites and how do I use them (for example in DB: sprite 1,x,y,1)?

  You can replicate the SPRITE function in DBclassic with the following.

PlayBASIC Code: [Select]

Function  Sprite(index,xpos,ypos,ImageIndex)
      Createsprite Index
      Positionsprite index,xpos,ypos
      Spriteimage index,ImageIndex
EndFunction

However i wouldn't recommend that !


  This is more appropriate,

PlayBASIC Code: [Select]

Function  Sprite(index,xpos,ypos,ImageIndex)
       if GetSpriteStatus(index)=false
      Createsprite Index
        endif
      Positionsprite index,xpos,ypos
      Spriteimage index,ImageIndex
EndFunction

I think that sorted it out. :) Thanks.
