I'm stuck ...
I put the sprite on the model.
The sprite itself is played when I throw the Entity.
Is it possible to delete a Sprite when the model touches the ground?
While the sprite is removed from the model together, when the model disappears over time
Also TE_BEAMFOLLOW does not suit me at all
And instantly deleting the model by touching the ground is also not good.

In other words: Remove the sprite from the model when touching the ground, but the model must remain on the ground until its time disappears.

Suddenly, if anything ...
