I am having a problem trying to make a bullet type animation where a Sphere (The Bullet) flies forwards really fast with keyframe type animation, then converts to dynamic animation, and shatters a vase.

The Sphere works fine in Cycles Render but has issues in Blender Game. Press P to play the animation, and you'll see what I mean.

After it shoots forward it suddenly stops, instead of going into Blender Dynamics it, slowly falls, and even goes through the floor.

If you need more information please ask.

Make sure you unzip the file. Thank you!

Due to an issue with recording the animation of the sphere I couldn't provide any animation or video.

  • $\begingroup$ Hi, it would be better that you explain what you did and why it doesn't work (maybe even add an animation or an image), and on this site it is suggested sharing .blend file on blend-exchange.giantcowfilms.com then pasting provided link in your question text. $\endgroup$

  • $\begingroup$ @m.ardito I just updated the information about the problem and the blend-exchange.giantcowfilms.com link, won't work for me. The website works just my blend file won't work for some reason. I'm new to Blender Stack Exchange. $\endgroup$ Oct 2, 2017 at 21:46
  • $\begingroup$ @Dimali I just fixed the link. Please Tell me if it works or not. Thanks! $\endgroup$ Oct 2, 2017 at 21:47

I change the physics of "Plane.001" to no collision, delete the action actuator and add a python controller, finally apply force on the bullet.

from bge import logic

enter image description here

Press P and see it!, you will need to take care of when the vase broke.


You can also go into the game logic menu and add an "Always" Sensor, an "And" Controller, and a "Motion" Actuator. Then just set the speed and you're done!
