Hi! I have created an entity that can be shot from a laser gun. However, when the laser hits the player, it stops rendering. It still hits the ground, though. If I move backwards really fast, it spawns in front of my face instead of inside, and renders until it hits an entity or block.

Sorry to post this twice. In my experience, though, once a post has been untouched for a day or more, it is most likely not going to be answered. Please help me with this: http://www.minecraftforge.net/forum/index.php/topic,8573.html If you can make heads or tails of my problem, thanks for being awesome! If you looked, but couldn't figure it out, thanks for trying! And if you didn't, well, thanks for at least reading my message.

Here are my other classes:
