How can I make objects follow player? Like our army follows us when we press a key?

Yes, you can use the AI command for this. Use the javascript function ccbAICommand(), and I guess there is also a downloadable action plugin for this available.

Yeah I already downloaded that. It's melee attack behavior.

I need:
Following behavior. For better understanding i am creating friend soldier so when we press 1st key they start following us and when we 2nd key they stop following.

Now understood?

I searched it found about moveto. But the problem is parameter is vector3D
can it be anotherNode? By creating var in that script?

Hello, behroz-khan!

I created an example for you to show you how to make a character follow a different character!

Download it here:
https://drive.google.com/file/d/...

When you open that CCB file with CopperCube, please press the "Publish" tab at the top, and then press the button shaped like a "Play" arrow to test the sample.

When the game starts, you can do this:
1. The cube named "Hero" can be moved with the arrow keys.
2. If you press the Z button, the cube named "Friend" will follow the other cube.
3. If you press the X button, the cube named "Friend" will stop following the Hero.

Study the file to discover how I did that.

Thank you very much!

I understood the script. I was really close I was doing one mistake.

Without you I was unable to do that.
The name of the file a futuristic person behroz-khan

He didn't make a script... but he uploaded a .ccb file to show what he did. Uses "Z" and "X" key to follow a cube named 'Hero'

Really depends on how perfect it must be. Most simple is to just move him a bit towards you every frame or so.

State of the art would be an A* pathfinding algorithm, that you implement in a behavior.

As a start, I'd suggest to add a behavior to the zombie: in proximity (to active camera) do something, when enter proximity, start a inFrame task, and on leaving proximity you'd unregister the task

//------ this

function onFrameTask()
{
me=ccbGetActiveCamera();
zombie=ccbGetSceneNodeFromName("zombie1");
// point zombie towards player
me_pos=ccbGetSceneNodeProperty(me,"Position");
zombie_pos=ccbGetSceneNodeProperty(zombie,"Position");
ang=Math.atan2(me_pos.x - zombie_pos.x, me_pos.z - zombie_pos.z)*57.29577951;
rot=ccbGetSceneNodeProperty(zombie,"Rotation");
rot.y=ang;
ccbSetSceneNodeProperty(zombie,"Rotation",rot.x,rot.y,rot.z);
// move him towards player
zombie_pos.x+=(Math.sin(ang)* 0.3); // 0.3 be the walking speed
zombie_pos.z+=(Math.cos(ang)* 0.3);
ccbSetSceneNodeProperty(zombie,"Position",zombie_pos);
}

ccbRegisterOnFrameEvent(onFrameTask); // this activates the zombie task

And in the "leave radius" proximity behavior you would then simply:

// ccbUnregisterOnFrameEvent(onFrameTask);

In the whole atan2 stuff you may have to switch some things by 180 degrees, until it works.
