Camera following a mesh

BlitzMax Modules Forums/MiniB3D/Camera following a mesh

ziggy(Posted 1+ years ago) #1
I've got this method on my 'camera' type, but I really don't like how it follows the 'main' character of the game I'm writing, I'm sure there will be a better algorithm for camera 'following' the main character. This is the code I'm using right now, any suggestion will be apreciated:

	Method Update()
		Local Dist:Float
		If target = Null Then Return
		Dist = cam.EntityDistance(target)
		
		If dist>maxdistance Then
			pos.PointEntity(target)
			pos.MoveEntity(0,2,0)
		ElseIf dist<mindistance Then
			pos.PointEntity(target)
			pos.MoveEntity(0,-2,0)
		End If
		pos.RotateEntity(0,0,0,True)
		
		cam.PointEntity(target)
	End Method


Notes:
Target is the mesh that has to be followed by the camera.
Pos is a pivot that is part of the camera object, it is used to place the camera.
cam is the camera object, contained as a filed on my camera type.

This is B3D code but should work with MiniB3D. It was coded by Antony and imo is a totally cool way for having a camera follow a mesh while avoiding obstructions.

mmm, any miniB3D version? I've not experience on Blitz3D

Well, Since MiniB3D IS B3D for BlitzMax then you should have no problem converting the code.

some nitwit by the name of 'bradford6' posted this 5 yrs ago:

so i went ahead and updated it for the animated robot demo


get the robot demo here:

or if you already have it, drop this code in the Robot Animtest folder
