while !place_meeting(x+hspd,y,obj_parede){
x +=sign(hspd)
}
hspd=0;
}

I saw it but I don't know how to update

The linked topic tells you how to update and even includes pre-2.3 and post-2.3 tables for comparison.

If you're having trouble with this despite that, post what you tried and we'll tell you where you took a wrong turn.
