Doodad's Animation

Does anyone know the string constant for a Doodad - Specifically a Tree - burning animation constant? I mean, there is a burning animation for a tree right? Coz I've seen it somewhere before.

Anyway, I want to let a tree be burnt and take damage over time. I was thinking of directly reducing its HP while its burning animation is played. Or having a dummy unit cast immolation on itself while the directly reducing the doodad's HP. But the second one cant work for reasons I dont know.

Can anyone help? Anyway, Im new here. Apologies if this is in the wrong section.

Just make a trigger that sets the health of the tree -x each second and create a fire sfx on top of it, trees in Wc3 do not have a burning animation. You might have seen a custom tree or a wc3 tree with a fire sfx on top of it.

The 'burning animation' is called the Fire doodad.
