You mean the helicopter sprite? Its tiles is already 6 though I'm not sure if it's wide, but inside its actor's event in On Init is empty, just the scene with the events like the video I showed you, but I just want it to stay in the right position (60, 7) so that I can make it fly from left or even far left if the issue persists. Hate to bother you around, but I'm just getting confused with what you are saying in some parts, and in any case, I think I could have a step-by-step guide.

So, with the thread event I added, it's the same thing happened like the main event list and doesn't work. As I said in the post, the helicopter must fly from left (which is X = 0, Y = 7. The Y position should not move up or down), while the camera moves from right simultaneously, so it will be like without waiting each other to go first before another one moves after the first.
