Precise positionning of doodads

[Ilmion]

I'm making a custom doodad similar to exit_teleport_boss_desert, so I'll use it has an example. I want to put my custom lock on it (which are the same size has the normal one. ie : boss_lock.png)
When I want to align the lock on the exit_teleport_boss_desert doodad, some lock do not align. Even at 1/8 grid size and at this point unchecking doesn't seem to let me move the lock doodad more freely.

I experimented a little and quickly found out that one "pixel" had a 0.125 increment in the vector positioning in the level xml. And has a matter of fact, when I change the position manually in the level xml, I can get the lock doodad in the right position. Which give something like : <vec2 name="pos">-9.9375 31.1875</vec2>

Here is the question (my first one here and my forst post) : Is the a better way to do it ? A way that would be in the editor ? Because if I move the doodad by accident in the editor, I have to move it manually again. It is not a big pain to do it manually because for now I only have this one case, but I'm curious.

Thanks

What does the sprite look like? You should not have to align anything in the xml, editor should be enough.

I have the same problem using the exit_teleport_boss_desert sprite and the boss_lock_1_small sprite.
In the attached image, example.png, you can see on the left the positioning I get with the editor. In which I am not able to put the lock completely in the yellowish circle. On the left, the positioning I want to achieve.

I have also attached my sprite which is basically a reskin of sort of the exit_teleport_boss_desert. The A are the place where I put the small lock doodad over.
The xml definition is a copy and paste of the exit_teleport_boss_desert one.

Edit : For the sake of putting everything here, I have also attached my lock sprite. They are made to spell"Alexandre" which is the name of my kid for whom I am making this little campaign and by the way learning my way around the map editing.

Ah ok, well, change the origin of the sprite with "1" vertical, positive or negative and it should work. It's because the smallest step in the editor is not 1 pixel, it's 2 =)

You can see the grid by pressing "0" in the editor and change the grid values with 1-9.

Thank you, that did the trick.
