I'm working on an assignment in which I have to make a sprite move. I've drawn each frame and I want to switch costumes to make it look like it's moving.
My block looks like this:
define walking
forever
switch costume to walk1
switch costume to walk2
And my code looks like this:
when *flag* clicked
forever
if key right arrow pressed? then
change x by 10
walking
But nothing is happening.
In order to figure out how this works, let's take a look at your code actually works. Here's your code in Scratchblocks.
So if you look at that, you'll notice there are two forever loops. Here's how your code is actually running:
when flag clicked
forever
if <key [right arrow v] pressed?> then
change x by (10)
forever
switch costume to [walk1 v]
switch costume to [walk2 v]
end
end
end
It gets stuck in the switch-costume loop once you've pressed the right arrow key! By removing the forever loop from your custom block definition it should be fixed.
When you put two blocks of "switch costume to[]" they will change very fast and for you will looks like they're not changing, so to be visible you need to put one timer after each block of switch costume and removing the forever block, like this:
when flag clicked
forever
if <key [right arrow v] pressed?> then
switch costume to [walk1 v]
wait 0.5 secs
change x by (10)
switch costume to [walk2 v]
wait 0.5 secs
end
end
to a better visual effect I put the change x by (10) in the middle of them See it in Scratchblocks
Simple fix: Remove the forever loop from the define block
define walking: â—„Fixed script
switch costume to (1)
switch costume to (2)
For even better graphics, you can do this:
When FLAG clicked
forever
if <key [right arrow v] pressed?> then
next costume
wait 0.1 secs
change x by(10)
end
end
