Animated Objects

[patrick]

Intro

It would look much better, if objects (like enemies, obstables, …) would not just pop up infront of the player as it is usual for oldskool vertical scroller games, but would fly in from behind or wherever. Look at this ​video and you will know what I mean

Goal

• Implement a scripting interface to enemy spaceships that gives the programmer a easy way to generate animated movements
• movement is defined by waypoints (3D vectors) in space and times they need to reach these
• the track is a numerical approximation: eg. bezier lines or splines

Information Gathering

• Be sure to watch this ​video, there you can see how ships enter the screen
• Read the article about ​splies from wikipedia
• Here you will find an old source code creating a track from some discrete points ​directory.

Implementation

• create a new Track class based on the old ​track system (just without forks/joins, and with adjustable/const speed)
• simple interface:
  • adding points for the track, time marks and movement functions (function of speed)
  • resetting the track
  • getting the position of an object moving on this track for a given time
• the track should be drawable for visualizing and debug reasons
