Sprites, frameproblems

Hey, forum!

I got a problem, probably an easy fix, but I can’t seem to figure it out.

  
require "sprite"  
  
local sheet2 = sprite.newSpriteSheet( "africanamerican.png", 32, 32 )  
  
local spriteSet2 = sprite.newSpriteSet(sheet2, 1, 12)  
sprite.add( spriteSet2, "man", 1, 12, 10000, 0 ) -- play 15 frames every 200 ms  
  
local instance2 = sprite.newSprite( spriteSet2 )  
instance2.x = display.contentWidth/2  
instance2.y = display.contentHeight/2  
  
instance2:prepare("man")  
instance2:play()

the problem is on line 5 “local spriteSet2 = sprite.newSpriteSet(sheet2, 1, 12)” when I change the frames that will be shown to 10, 12, I get an error saying “sequence frames must be inside the sheet”.

It works fine when i type 1, 12 or any other combination not including double digits in the first frame shown.

Also, my sprite has 12 sheets.

Please help me!

sprite.add( spriteSet2, “man”, 1, 12, 10000, 0 ) – play 15 frames every 200 ms

if you want to play only 11 and 12 then above line should be

sprite.add( spriteSet2, “man”, 11, 12, 10000, 0 )

and if want to play after 200 ms then

sprite.add( spriteSet2, “man”, 11, 12, 200, 0 ) [import]uid: 12482 topic_id: 9846 reply_id: 35878[/import]

You should read the API more carefully: sprite.add

startFrame
Number: The number the first frame in the sequence.

frameCount
Number: The total number of frames in the sequence. If frameCount is negative, the sequence starts playing backwards. For example, startFrame = 3 and frameCount = -3 will play frames in a 3, 2, 1 order.

It’s not “endFrame” but “frameCount”.

Correct code:
[lua]sprite.add( spriteSet2, “man”, 10, 3, 10000, 0 )[/lua] [import]uid: 51516 topic_id: 9846 reply_id: 35879[/import]

nice one i really take that as “endFrame”

but now as i had got right thing i am in trouble

this is my basic code runs 1 to 15 frame perfect…

[lua]local eagleSprite = sprite.newSpriteSheet( “eagle.png”, 55, 95, 15 )
local eagleSprite_set = sprite.newSpriteSet(eagleSprite, 1, 15 )
sprite.add( eagleSprite_set, “eagleSprite_set”, 1, 15, 500, 0 )
local eagle = sprite.newSprite( eagleSprite_set )
eagle:prepare(“eagleSprite_set”)
eagle.x = 512
eagle.myName = “eagle”
eagle.y = 240
eagle:play()[/lua]

now edited line 3

sprite.add( eagleSprite_set, “eagleSprite_set”, 10, 5, 500, 0 )

which runs frame 10 to 15

again edited
sprite.add( eagleSprite_set, “eagleSprite_set”, 10, 1, 500, 0 )

only frame 10

but now ,

sprite.add( eagleSprite_set, “eagleSprite_set”, 15, -10, 500, 0 )

got the error

even whenever i give negative number i got error why?? [import]uid: 12482 topic_id: 9846 reply_id: 35886[/import]

That’s what you get for not paying attention in Math classes :slight_smile:

sprite.add( eagleSprite_set, “eagleSprite_set”, 10, 5, 500, 0 )

which runs frame 10 to 15.

Wrong. Frame 10 to 14.
[lua]local eagleSprite_set = sprite.newSpriteSet(eagleSprite, 1, 15 )[/lua]

15 sprites. That’s sprite 1 to sprite … 14.

Correct code:
[lua]sprite.add( eagleSprite_set, “eagleSprite_set”, 14, -10, 500, 0 )[/lua] [import]uid: 51516 topic_id: 9846 reply_id: 35888[/import]

nope dude not working

sprite.add( eagleSprite_set, “eagleSprite_set”, 14, -10, 500, 0 )

not even

sprite.add( eagleSprite_set, “eagleSprite_set”, 14, -5, 500, 0 )

and about my maths its a terrible :):):):):slight_smile: [import]uid: 12482 topic_id: 9846 reply_id: 35890[/import]

i had also same issue with jungle scence example

on line 68 i was unable to run with negative number

sprite.add( spriteSet1, “cat”, 1, 8, 1000, 0 ) – play 8 frames every 1000 ms

any negative number instead of 8

or do i need to change anything else which i am not changing

can u plz tell me where to change in that example to run with negative number [import]uid: 12482 topic_id: 9846 reply_id: 35892[/import]

If you’re sure about your sprite frame number, there is nothing more I can do. File a bug report with Ansca and hope for the best. [import]uid: 51516 topic_id: 9846 reply_id: 35894[/import]

#9

nope dude not sure as you can see till now i was treating as endframe instead of framecount

and about my spritesheet i need to play it from 1 to 15 no need of negative number as i am playing all the images

and reason for the jungle scene example is due to we both have same example i had just changed line 68 as given below

sprite.add( spriteSet1, “cat”, 7, -3, 1000, 0 )

and getting error so just want to know

thanks and bye :slight_smile: [import]uid: 12482 topic_id: 9846 reply_id: 35896[/import]
