place_meeting not working?

[corwin22]

This is the code I am using and both objects have a mask
if (place_meeting(x,y,obj_orb))
{
hp = hp - 1
}
but it doesn't work at all
the strange thing is that the orb with almost the same command
if (place_meeting(x,y,obj_Wall)) {
instance_destroy()
}
and it works so i am pretty confused?

Could be that the orb's code runs first. It checks for collision and destroys itself. Then the wall checks - nope, no collision because the orb no longer exists.

hp = hp - 1

Also, not related to your issue directly, but change this to

hp -= 1;

Or more preferably,

hp --;

The second code will minus one just the same, and the first one is the better way to write it if you ever subtract more than one, for example

hp -= 5;
