Objects rotate on their origin points , so make sure the hands on your clock have an origin point at its end , or close to it.

Use a global variable, Space is down , every (global variable) , do something , on collision with powerup , decrease global variable by what ever you want.

Check out the custom movement behavior in the manual , it might be what you are looking for ?

Touch conditions

Compare acceleration

Compare the current device's motion as its acceleration on each axis in m/s^2 (meters per second per second). The effect of gravity can be included or excluded, but note that some devices only support accelerometer values including the effect of gravity and will always return 0 for acceleration excluding gravity.

Compare orientation

Compare the device's current orientation, if the device has a supported inclinometer. Alpha is the compass direction in degrees. Beta is the device front-to-back tilt in degrees (i.e. tilting forwards away from you if holding in front of you). A positive value indicates front tilt and a negative value indicates back tilt. Gamma is the device left-to-right tilt in degrees (i.e. twisting if holding in front of you). A positive value indicates right tilt and a negative value indicates left tilt.

The field of view in LOS is based on the objects current angle , so you will have to change this and not just mirror the object for it to work correctly . The manual is specific on this subject.

To get them to spawn randomly just make an event, every x seconds and add the action create object.

X: random(3000)

Y: random(3000)

Or use what ever coordinates you want.

Enemy has LOS to Player and then a subevent that checks if clockwise ,rotate to position , then a else subevent and rotate the other way , works for me !!!

line of sight lets you limit the cone of degrees , have you checked into using it ?

Rotate toward position and use a negative number for ccw ,worth a try ?????

What do you mean by unzipping files , if you are talking about .cap files then just double click on them and construct will load them .

Right click on your first condition and then choose add condition and insert another condition , you can have multiple conditions . Read manual on conditions in events.

The easiest way and without any conditions or actions would be the sine behavior added to the object , the manual will explain it quite well.
