How animate Sonic here?:
https://scratch.mit.edu/projects/1257954364

Make 4 consecutive costumes R-Run1, R-Run2, R-Run3, R-Run4.
Also make 4 consecutive costumes L-Run1, L-Run2, L-Run3, L-Run4 by reflecting the costumes in the editor.

Then the code below will cycle through the costumes.
(It replaces your current code for Run at the end of your My Block “paint sprite”.

if <<(action) = [Run]> and <(direction) = [R]>> then
if <<(costume [name v]) = [R-Run1]> or <<(costume [name v]) = [R-Run2]> or <(costume [name v]) = [R-Run3]>>> then 
next costume
else
switch costume to [R-Run1 v]
end
end
if <<(action) = [Run]> and <(direction) = [L]>> then
if <<(costume [name v]) = [L-Run1]> or <<(costume [name v]) = [L-Run2]> or <(costume [name v]) = [L-Run3]>>> then 
next costume
else
switch costume to [L-Run1 v]
end
end

It's preferable not to check for the current costume, especially when they all end with a convenient number. To run through each costume in a run cycle, you can do

when I receive [tick v]
set [runframe v] to (((runframe) mod (number of frames)) + (1))
switch costume to (join [Run] (runframe))

Of course this isn't all, this goes in with the rest of the script that decides what actions are taken. If you want the animation to speed up as the player runs faster, decide the frame based on the amount of distance the player has traveled e.g. next costume every 18 units of distance.

change [runframe v] by ([abs v] of (xvel)::operators)
switch costume to (join [Run] ((([floor v] of ((runframe) / (dist before next frame))::operators) mod (number of frames)) + (1)))

1. OMG, it's that really you @Scratch-Minion!?!?!?!? Cool!

Now, what you purpose for 0.0.3?

PLANNED FOR FUTURE

-Add sounds
-Add a proper spin
-Add spindash

Hi again.

Just a note that I thought you would use the four existing costumes Run1, Run2, Run3, Run4 in the sprite for the right running Sonic costumes.

There's only 4 anims used for each direction: for left: L-Run1 and L-Run2; and for right: R-Run1 and R-Run2

Hi,
Anyone knows how can I have the solution to this issue in 0.0.4?:
