You simply need to change .1 in the following line to a greater number. It will depend on the size of your entities and the distance of the camera.
TranslateEntity camera,-dx*.1,(-dy*.1)+2,(-dz)-30
The higher number you use the less lag between your entity and the camera. Perhaps try something like this.
TranslateEntity camera,-dx*.1,(-dy*.1)+2,(-dz)-30
The higher number you use the less lag between your entity and the camera. Perhaps try something like this.
lag# = .7 ;<----trial and error will get this right for you. TranslateEntity camera,-dx* lag# ,(-dy* lag# )+2,(-dz)-30
