How Can I Make a Sprite Change Costumes When It Moves?

LittlePony

I've been on scratch for a long time, but I never made a platformer or anything that required a sprite to move with costumes, but I'm making a game now that requires this. So, would someone explain to me how to make the costumes do this. I already have the movement down like, forever if right arrow pressed make x -5 the costumes are all I need.

Oh, so you're trying to figure out how to make it move with an animation using costumes? Well, you could say, “forever is right arrow pressed change x by -5 next costume.” Or you could set the costume to a variable, and constantly change that variable when the key is pressed. (But with a variable you'd need to make it so if it gets bigger or smaller than the amount of costumes, it goes back to one, so then it loops.)

As always, I hope this helps!

The sprite will go up, down,left, and right, so next costume wouldn't work. As for the variable, It wouldn't work out so well either…(I think)

Oh, I didn't know that part.

One thing you could do is have scripts sepertated so they run at the same time. It would look like this:

When GF clicked
forever

if <button [up] pressed>
switch to costume [up1]
wait (0.5)
switch to costume [up2]
wait (0.5)

if <button [down] pressed>
switch to costume [down1]
wait (0.5)
switch to costume [down2]
wait (0.5)

And so on…

(And of course, there would be the changing x or y part when a button is pressed, but in a seperate script.)

I hope this solved your problem!

Can you link what you have so far?
Thanks!

Yes, that would be helpful. It always is, because then we could see your problem.

It's pretty tough to explain here, however I have made a project like this before. Feel free to analyze what I have and even use my system, but just give credit in the notes if you use the exact project.

Note: This method can be glitchy at times when changing directions
Happy scratching!

I remixed JayZX535's project to use a timer based animation on the wolf. It keeps the code a little cleaner, allows you to adjust the animation speed with 1 variable, and allows your sprite to respond to input more quickly because it doesn't have all the “wait” statements.

Timer based wolf animation

You could do something similar with the grass on that project as well.

^This is the updated method of my original project, and is actually my preferred method as well. Thanks for re-mixing, because I didn't really have any examples for it yet! And yeah, from what I've found, this method is pretty safe/reliable (unless you have multiple sprites running on the arrow keys at once because then you get lag, but that's generally not a problem).

i could really use some help too, because.. http://scratch.mit.edu/projects/17377323/ happens

SCRATHCREATOR950

when green flag clicked
forever
    
glide (1) secs to x: (RANDOM NUMBER) y: (RANDOM NUMBER)
next costume
end

i need help making a game where you move and animate at the same time without the screen moving. the best results i got were a really long delay between animation strings. here is the project http://scratch.mit.edu/projects/24837636/

Just_A_Dream

You do this:
when flag is clicked
move ___ steps

when flag is clicked
switch to next costume

olesijk1

d

when green flag clicked
forever
if key right arrow pressed then
wait 0.2 seconds
next costume
change x by 10

olesijk1

when green flag clicked
forever
    
if <key [ v] pressed?> then
wait  secs
next costume
change x by ()
    
end

end

X value = -5

That's left not right lol.

pickleoink

make another script that says

when green flag clicked
forever
    
switch costume to [costume 1]
wait (.1) secs
switch costume to [costume 2]
wait (.1) secs
end

upupup3

This is how

[scratchblocks]

when [ v] key pressed
[/scratchblocks][scratchblocks]

forever
    
if <key [ v] pressed?> then
point in direction ( v)
    
move () steps
next costume
end
end

[/scratchblocks]

ILuvNintendo

I want to know to because when I try

when green flag clicked
set rotation style [left-right v]

define Controls
if <key [right arrow v] pressed?> then
point in direction (90 v)
next costume
move (10) steps    
if <(costume #) = [ 1]> then
    
switch costume to [2 v]
end

end

It doesn't work
