Hello!

 

I'm currently porting an ancient Minecraft 1.2.5 mod to 1.4.6 for a private server. I've got everything to work perfectly except this one bug I can't seem to squash.

 

When I place the block down, it appears perfectly fine.

Until, that is until I save and load the world again. The block is.. floating??

Okay, I fixed that issue.. But I have another one. I fixed the rendering issue by blanking out setBlockBoundsBasedOnState().

Now, sometimes on save + reload, the gel doesn't work (e.g. Repulsion Gel doesn't make you bounce high when stepping on it/hitting the jump button) or it works improperly (Propulsion Gel only speeds the player up for a few moments)

 

Through debugging, stepping on repulsion gel seems to get all the way:

 

						
...
                                                else if (!var5.isSneaking())
					{
						if (var5.motionY < 0.0D)
						{
							var5.motionY = 0.0D - (var5.motionY - 0.30000001192092896D);
							var9 = true;
						}
						else
						{
                                                                // Here, but all of the if statements never pass and adds motion.
							if (var5.motionX > 1.0D)
							{
								var5.motionY = 1.0D;
								var5.motionX = 2.0D;
								var9 = true;
							}

							if (var5.motionX < -1.0D)
							{
...

 

Thanks!

 

Edit: The above information might not be correct...

I think I've found part of the problem: Entity.motionY. It gets set, but the player never ever ever EVER has motion on the y axis even if it's set to have it. Any ideas, anybody?

 

Thanks.

 

Also, the above is wrong: it runs into in the if statement (var5.motionY < 0.0D), and it passes, so it sets motionY.
