I have two objects, Object A and Object B. Object B can be constantly moving whatever I set its position to be, or it's movement. It could also not be moving at all. I want to be able to make it so that Object A chases Object B (by moving towards it every frame) at a constant speed where if Object B changes position, Object A's direction of movement changes as well. I am using normal Blender Render, so can someone suggest me an easy way to do this, even if it involves Python coding. It's basically making an object face another and translating on its own local forward.
Want I don't want is the two objects two have their vertex positions linked to each other so if I drag one in the editor, the other one will move as well (aka parenting). I do not want that.
This means that if Object A's speed is set to 0, then changing Object B's position won't affect Object A's position.
Again I want that so as I play the animation frame by frame, the first object is moving towards the second object at a constant speed and the second object itself can move somewhere else which will change the heading of the first object in order to still be following the second object.
