Got some questions about direction and collision

Hey ClickTeam Community,

After following a few tutorials i thought it was time to make my own small game.
The basic idea of the game is, as the player to protect your family of incoming enemies.

I am strugeling with a few things:
-Enemies wont spawn randomly at the preset spawnpoints
how can i make the enemies spawn more often and more randomly without preset spawnpoints?

-The direction of the enemies wont go in a straight line towards the family
how can i make the direction in a straight line to the family?

-When the player collides with the enemy the enemy still goes towards the family and doesnt bounce back, only the player does
how can i make the bounce of the enemy just bounce or make the bounce bigger?

Thanks for the help

Figured out to spawn enemies at spawners, yay to me
