Warning message when using sprite

bpran · October 21, 2012, 12:50am

I am new to corona,
I am experimenting with sprite right now.

I receive 2 warning with same message when I wrote the codes below:

spriteSheet = sprite.newSpriteSheet("images/wheelmenu.png", 80, 80);  
 spriteSet = sprite.newSpriteSet(spriteSheet, 1, 16);  
 sprite.add(spriteSet, "turn", 1, 16, 1000, 0);  
  
 local wheel = {};  
 wheelGroup = display.newGroup();  
 for loopY = 1, 12 do  
 wheel[loopY] = sprite.newSprite(spriteSet);  
 wheel[loopY].x = (loopY \* 80) - 200;  
 wheel[loopY].y = 120;  
 wheel[loopY]:prepare("turn");  
 wheel[loopY]:play();  
 wheelGroup:insert(wheel[loopY]);  
 end

the warning is at line 3 and 8 and the message is:
Class Mismatch. Expected class of type: SpriteSheet got:SpriteSet

The codes above still run as what I expected, but I am curious why I got those warnings.

I think you may be using the old API’s. Make sure they are the most recent ones…if not then I have no idea. [import]uid: 29181 topic_id: 32164 reply_id: 128055[/import]

I don’t understand what you mean by “old API”,
what I did was put this on my top line:

sprite = require ("sprite")

do you mean I have to put some .lua file inside the project folder?
I am using the latest public release version build 2012.894 ( I am subscribed member).

thank you for the reply. [import]uid: 31508 topic_id: 32164 reply_id: 128057[/import]

The code you’re using is deprecated. Use the new sprite code - it’s much better and versatile.
Here is the API for the new sprite code–> http://docs.coronalabs.com/api/library/display/newSprite.html

Hello @bpran,
Here’s a tutorial I wrote recently about the current sprite system… a step-by-step walk through.

And here’s another tutorial about advanced sprite tips and tricks which you might find useful after you learn the basics:

@All,

Thanks for your help, it is greatly appreciated!

@bpran,
Let us know after using the new sprite API the warnings disappear. The context based autocomplete is best designed for use with the new sprite system.
