Enemies not dropping

so in my endless runner i have placed enemies that are spawned above the the tiles but the problem is that they are not dropping. i have enabled the gravity but it doesn’t solve the problem. they just stay in the air

this is my EnemyAI

Are your enemies based off of one of the default actor types (Like a character?).

Also, make sure you have all of your collision set up for the root component with physics enabled.

you are calling *set timer by function Name * but you are have set up an Event
have you tried it with a simple static mesh instead of a complex bp?

My enemies are based off of the wheeled vehicle types i have also enabled my my collisions:

but i still face the same problem

sorry i don’t understand what you mean? i changed the timer condition but im still facing the same problem. i just i dont get your other question
