How do I Make a sprites angle follow the mouse?

Hello, I would like to know how to make a sprite set it's angle to the mouse position without it using the origin point. I would like ti to use Image point 1 for example.

Also, I need the player character, who is using an 8 directional movement behaviour, to move in the opposite direction of the mouse when clicked. Like it's being pushed.

Thank you

use the function angle()

so one way is:

onMouseClick
Set Sprite Angle to angle(sprite.x,sprite.y,mouse.x,mouse.y)

to give your player a "boost" give it bullet behavior (in addition to 8dir.

Set Bullet Default Speed to 0 and Acceleration to -1600 and uncheck Set Angle

Then:

OnMouseClick
Set Bullet Speed to 400
Set Angle of motion to angle(sprite.x,sprite.y,mouse.x,mouse.y) - 180

If you are looking to set the rotation based on the angle between your sprite's imagepoint 1 and the mouse, use the solution that jobel gave but change the sprite.x,sprite.y to sprite.imagepointX(1), sprite.imagepointY(1)
