********************************

 

A camera that will follow the entity that is moving in the X axis :

 

**********************************

 

1) in App.lua declare the global camera entity :

 

 

function App:Start()

...

--Create a world

f.world=World:Create()

...

camera = Camera:Create()

camera:SetRotation(35,0,0)

camera:Move(0,0,-30)

...

return true

end

 

 

 

2) in the character AI lua script in the updatePhysics loop just add these lines :

 

 

function Script:UpdatePhysics()

 

local time=Time:GetCurrent()

 

self.entity:GoToPoint(20,0,-15,1.4,1);

 

xpos=self.entity:GetPosition().x

 

camera:SetPosition(xpos,10,-30)

 

self.entity.animationmanager:SetAnimationSequence(self.sequence.walk,0.04,200)

 

end

 

 

******************

 

How it works :

 

We get position in X axes of the character that is moving by calling :

xpos=self.entity:GetPosition().x

 

Then we change camera position in X axis with the value of the character in X axis :

camera:SetPosition(xpos,10,-30)

 

So the camera will follow the character in the X axis as it moves.

 

You can extend the script and do the same with Z value or Y if the character would climb some stairs.
