Is there anyway to update an entity’s position each and every frame to be in the exact same position as another entity??
Thanks in advance 
Not sure why you want to do that, but run this and tap the screen to move the position of the blue ball to the same position as the red ball. If you want to do that every frame, then instead of the line of code in touched, it would be in draw.

Do you think you could edit my code and implement it in for me please??
Thank you
Any asset you have in your Dropbox folder is an error for me because they’re not available to me.
What objects in your code are you trying to reposition to match another object.
I’m trying to reposition the blaster object so that every frame it’s position updates to be where the scene.camera is
I did a search for blaster and all I found was an empty function makeBlaster. I did a search for scene.camera and it’s all over the place. I’m not sure how much help I can give you because I can’t run the code and I don’t know what your program is supposed to be doing.
All the assets you have in Dropbox should be moved to the folder for that project. Tap on one of the assets to bring up the asset list and the project folder should be the top folder. Once all of you assets are in its project folder, you can zip the project and it will contain all of the assets you use. That zip file can be posted in the forum instead of the code and anyone would be able to load it and have everything they need to run it.
To move assets from the Dropbox folder, while in your code, tap a Dropbox asset to bring up the asset list. Get into Dropbox. Tap edit and select assets to move. Then tap add and it will ask you where you want to copy them. Select your project folder.
