Thank you for your help, but i don?t understand
it complete how you explain...
"Edit the sprite and delete the collision mask"
Do you mean the collision mask sprite, or one the player sprite?
"then click on collision mask again and close and save"
There you mean the c-m sprite, do you? But you have to edit it to close and save.
And after that i have to copy the cm to each frame.
That?s what i?ve done, but it doesen?t work.
"a dummy sprite with the platform behavior and set the position of the main sprite to this using System: always set position to object."
I don?t understand it. How do i do this?
Sorry if that are silly questions, but i?m a beginner.
Maybe the Tutorials explains it too.
Anyway, i look to them.
