Well I am using stamped objects instead of clones and need to know how they detect collisions with each other and no I cannot use a

<color [#cbdbf5] is touching [#49e84b] ?>

since The two objects are gradients pls help!

You can solve it with something like this…

when green flag clicked
forever
if <<key [... v] pressed?> and <not <touching [Barrier v] ?>>> then
move (...) steps //Or change x, or y... whatever
end
end

They're saying that they are using stamps instead of clones here. However, you can still use the (touching) block with a 2nd sprite, which would not be a clone.
Though If you prefer all stamps, you could make the sprite invisible via ghost effect and still detect as another sprite1 touching sprite2, I guess, before you do your stamping process.

maybe something like this, as an example.

when green flag clicked
forever
clear all stamps
move objects
check collisions
do stamping process
... // Etc...
end

you have to predict if the player is going to move into a tile/sprite spot using lists and then set the x or y velocity to 0 accordingly
