[SOLVED][1.11.2] Rotating Entities using RenderLivingEvent


Furgl

Recommended Posts

Hello. I'm trying to rotate other entities (not my custom entities - I don't have access to their model/render classes to do this with easily) to be upside down. I have found several posts about similar topics, but none that I found had a valid solution or had been closed before a solution was posted.

 

Currently, I'm able to rotate an entity properly, but the entity then moves along the y-axis incorrectly as the player moves (note: the polar bear is on top of the glass block):

Here is my current code: 

@SubscribeEvent
@SideOnly(Side.CLIENT)
public void rotateEntities(RenderLivingEvent.Pre<EntityLivingBase> event) {
    if (/*should this entity be rotated*/) {
        GlStateManager.pushMatrix();
        GlStateManager.rotate(180f, 0, 0, 0);
        GlStateManager.rotate(180f, 0, 1, 0);
    }
}

@SubscribeEvent
@SideOnly(Side.CLIENT)
public void rotateEntities(RenderLivingEvent.Post<EntityLivingBase> event) {
    if (/*should this entity be rotated*/) {
        GlStateManager.popMatrix();
    }
}

 

If anyone knows how to fix this y-axis movement (i.e. a translation) or how to properly rotate the entity so this doesn't happen, please let me know. Thanks ahead of time!

After some experimenting, I found that a simple translation fixes it:

@SubscribeEvent
@SideOnly(Side.CLIENT)
public void rotateEntities(RenderLivingEvent.Pre<EntityLivingBase> event) {
    if (/*should this entity be rotated*/) {
        GlStateManager.pushMatrix();
        GlStateManager.translate(0.0F, event.getY()*2f+event.getEntity().height, 0.0F);      
        GlStateManager.rotate(180f, 0, 0, 0);
        GlStateManager.rotate(180f, 0, 1, 0);
    }
}

@SubscribeEvent
@SideOnly(Side.CLIENT)
public void rotateEntities(RenderLivingEvent.Post<EntityLivingBase> event) {
    if (/*should this entity be rotated*/) {
        GlStateManager.popMatrix();
    }
}

As mentioned previously...

 

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
