How do I change in time bullet speed .....

Hi guys, I would like NOT to use phiscs...if my player shoots a bullet it should become slower and loose bounce strength and gravity,.,...how can I do that only with bullet behaviour ?

thanks

You mean like this:

you could do it like this

thanks to both is that possible also after every bounce ?

first bounce -50 2cond -100 ecc....

yes it is up to you to code that way
