How to make an object follow the camera and stop following when that object collide with a wall or another object or when camera activates another object?

For my student project, I need to know how to do this purely using either javascript or blockly. I got the idea from my classmate but his code doesn’t either. Thanks for all helps appreciated!

I am very new to CoSpaces, but I tried the following to do what you need.

Setup

I placed the boy character in the view of the camera. I added a cuboid at the same position as the camera. Finally, I attached the boy to the cuboid; this way, wherever the cuboid goes, the boy will follow. This is what it looks like in creation mode:

Code

The idea is to make the cuboid to follow the camera. Since I could not find a way to attach the character to the camera, I decided to have the cuboid follow the camera using the update block.

Notice that I first make sure the cuboid and the camera start at the same location. Then I set the location of the cuboid to the same location as the camera with each update call.

When you move with the WASD keys, the boy follows:

Problem

Even though the boys seems to follow the camera with the WASD keys, everything falls apart when you try to turn the camera. There does not seem to be a way in CoSpaces to have one object to adopt the direction of another. There is a “direction of” block, but I do not see where to use it.

Please ignore my previous post.
It turns out that you can actually attach a character to the camera using the object tree.

Here are the info (see Stefan’s post on May 3rd)

Camera attached to the point of view

I program a virtual reality game in which you have lifes. My problem is that I want to fix the lifes on the camera so that you can see them every time, for example when looking up to the sky, right or left, you should be able to see them all the time.
