When u do this:

Code:

welle = {   w1=Image.load("wave0000.jpg"),
      w2=Image.load("wave0001.jpg"),
      w3=Image.load("wave0002.jpg"),
      w4=Image.load("wave0003.jpg"),
      w5=Image.load("wave0004.jpg"),
      w6=Image.load("wave0005.jpg"),
      w7=Image.load("wave0006.jpg"),
      w8=Image.load("wave0007.jpg"),
      w9=Image.load("wave0008.jpg"),
      w10=Image.load("wave0009.jpg"),
      w11=Image.load("wave0010.jpg")  }


U should use:
Code:

welle = {   [1]=Image.load("wave0000.jpg"),
      [2]=Image.load("wave0001.jpg"),
      [3]=Image.load("wave0002.jpg"),
      [4]=Image.load("wave0003.jpg"),
      [5]=Image.load("wave0004.jpg"),
      [6]=Image.load("wave0005.jpg"),
      [7]=Image.load("wave0006.jpg"),
      [8]=Image.load("wave0007.jpg"),
      [9]=Image.load("wave0008.jpg"),
      [10]=Image.load("wave0009.jpg"),
      [11]=Image.load("wave0010.jpg")  }


and...when u use:

Code:

screen:blit(38,20,welle["w" .. wave])


Change to:

Code:

screen:blit(38,20,welle[wave])


Do the same thing with ur "player_straight"...

Regards,

thx,not really the answer but helpful anyways, i'm trying an approach with keyframes right now.

how can i check if a division by a certain number leaves a rest, say .034 or so or not? that would be the key...

I (AS A TOTAL NOOB!) DID IT!

i made a function that works with a keyframe concept, check it out!

Code:

-- objects

timeline=1000
frames=1

object = {wave,straight}

player_straight = {    [1]=Image.load("s1.png"),
                   [2]=Image.load("s1.png"),
                  [3]=Image.load("s3.png")   }

welle = {   [1]=Image.load("wave0000.jpg"),
      [2]=Image.load("wave0001.jpg"),
      [3]=Image.load("wave0002.jpg"),
      [4]=Image.load("wave0003.jpg"),
      [5]=Image.load("wave0004.jpg"),
      [6]=Image.load("wave0005.jpg"),
      [7]=Image.load("wave0006.jpg"),
      [8]=Image.load("wave0007.jpg"),
      [9]=Image.load("wave0008.jpg"),
      [10]=Image.load("wave0009.jpg"),
      [11]=Image.load("wave0010.jpg")  }

function frameskip(objectnumber,frame,limit)
--is frame nil or zero?
   if frame==0 or frame==nil then
      frame=1 end

--is object==nil?
if object[objectnumber]==nil then
   object[objectnumber]=1 end

--frames for every timer : 1000-->reset follows
--how many times is timeline dividable by frame?
   res=math.floor(timeline/frame)

   for i=1,res do
      if i*frame==frames then
         
         -- increase object[..] by 1
         -- test if limit of animation steps is reached
      
         object[objectnumber]=object[objectnumber]+1

            if object[objectnumber]>limit then
               object[objectnumber]=1
            end
      end
   end


--count++ & reset the timer if >timeline
frames=frames+1
if frames>=timeline then frames=1 end

number=object[objectnumber]

return number

end

function anim_surfer()
   
   pad=Controls.read()
   
   if pad:left() then
      if xpos>=50 then xpos=xpos-10 end
      screen:blit(xpos,ypos,player_left,true)
      
   elseif pad:right() then
      if xpos<380 then xpos=xpos+10 end
      screen:blit(xpos,ypos,player_right,true)
   
   elseif pad:up() then
      frameskip(2,60,1)   

   else
   
   -- straight movement, three animation steps
      
      frameskip(2,20,3)
   
      screen:blit(xpos,ypos,player_straight[number],true)
       end

end




so objectnumber is 1 for wave and 2 for straight (movement of the surfer)
frame is at which frame and x*frame the change in the animation step occurs
limit is the number of animation steps

hope someone likes it :)

any suggestions??
