How would I go about doing the following:
If X on client, do Z on server.
So basically, check something on the client, and do it on the server if it is right. Afaik I can't use the world.isremote idea because as soon as I check client it won't be able to check server again within the if statement.

When they are swimming, they call a method called moveFlying() ("flying" is used for both swimming and flying because it means gravity is active on entity) which is called by moveEntityWithHeading(). In that method it also checks for the isAIEnabled() so you have to override that one as well. This is what the current class looks like:
public void moveEntityWithHeading(float par1, float par2)
{
double d0;
if (this.isInWater() && (!(this instanceof EntityPlayer) || !((EntityPlayer)this).capabilities.isFlying))
{
d0 = this.posY;
this.moveFlying(par1, par2, this.isAIEnabled() ? 0.04F : 0.02F);
this.moveEntity(this.motionX, this.motionY, this.motionZ);
this.motionX *= 0.800000011920929D;
this.motionY *= 0.800000011920929D;
this.motionZ *= 0.800000011920929D;
this.motionY -= 0.02D;
if (this.isCollidedHorizontally && this.isOffsetPositionInLiquid(this.motionX, this.motionY + 0.6000000238418579D - this.posY + d0, this.motionZ))
{
this.motionY = 0.30000001192092896D;
}
}
else if (this.handleLavaMovement() && (!(this instanceof EntityPlayer) || !((EntityPlayer)this).capabilities.isFlying))
{
d0 = this.posY;
this.moveFlying(par1, par2, 0.02F);
this.moveEntity(this.motionX, this.motionY, this.motionZ);
this.motionX *= 0.5D;
this.motionY *= 0.5D;
this.motionZ *= 0.5D;

So you need to override the whole method and change the line near the top where it checks if isAIEnabled().
Regarding the rest of your comments about AI, I'm in the process of writing a tutorial on it. There are a couple of tricks related to how you disable AI when other AI is running (the setMutexBits() method is used but it is a little tricky without explanation) as well as the priority order you have the task list.
How do you adjust the priorities on the task list? Also, it worked, thanks!
-
I've always used the new AI so never really looked at this before. However, looking at it quickly it seems that you probably need to look at overriding at the following:
In your entity class, maybe Override the getAISpeed() method. In the EntityLivingBase class, the method is defined as:
public float getAIMoveSpeed() { return this.isAIEnabled() ? this.landMovementFactor : 0.1F; }So just change that 0.1F to what you want. Not sure but that might do it.
Modified what you suggested a little bit and it work now, except when they go in water. I removed the this.landMovementFactor because it wasn't a variable that was recognized.
Also, the problem with new AI is it seems to cause my mobs to randomly lose aggro on the player, and when I adjust the movement speed they don't face the way they are running.
-
So, the line:
this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(value);
doesn't seem to change anything unless the new AI is enabled. However, with new AI enabled, it really messes with some of the things I've added. Is there a good way to make it move faster otherwise
I've tried doing all sorts of adjustments of movement speed in the onLivingUpdate tick.

Hi
Some background information here that might help
http://greyminecraftcoder.blogspot.com.au/2013/08/rendering-items.html
and linked pages eg
http://greyminecraftcoder.blogspot.com.au/2013/08/rendering-inventory-items.html
-TGG
The thing is, there is no custom render. Some of them work fine, some just don't.

So when I look at the block in my inventory, it doesn't appear as a cube from a 45 degree angle like Vanilla blocks, I just see the straight up texture.
My block class:
public class BarColors extends Block {
private String name;
private static Material BCLR = Material.iron;
public BarColors () {
super(BCLR );
this.setCreativeTab(mineandbash.CageTab);
this.setHardness(5f);
this.setResistance(0.5F);
this.setLightLevel(0.0F);
}
public Block setTextureName(String name){
return setBlockTextureName("mineandbash:" + name);
}
public Block setName(String name){
this.name = name;
setBlockName(name);
setTextureName(name);
GameRegistry.registerBlock(this, name);
return this;
}
}
-
To load textures:
@SideOnly(Side.CLIENT) @Override public void registerIcons(IconRegister iconRegister) { iconBuffer = new Icon[MetaCount]; iconBuffer[0] = iconRegister.registerIcon("MODID:" + TextureName1); iconBuffer[1] = iconRegister.registerIcon("MODID:" + TextureName2); blockIcon = iconBuffer[0]; }To get textures based on meta:
@SideOnly(Side.CLIENT) public Icon getBlockTexture(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5) { return iconBuffer[par1IBlockAccess.getBlockMetadata(par2, par3, par4)]; }Is this for 1.7 (I'm asking about 1.7)? Cause I get errors galore (of unimportable things, such as IconRegister -- Did you mean IIConRegister?).
edit:
So I found a way to have more than 16 versions (infinite really) of the block in one file, as I just make it a new type of block.
-
Write this in your class, that's the simple way
public void setMeta(World world, int x, int y, int z, int meta) { world.setBlockMetadataWithNotify(x, y, z, MathHelper.clamp_int(meta, 0, 3), 2); world.func_147453_f(x, y, z, this); }Okay, thank you, but how do I change the texture of the block depending on the meta data, as well as use metadeta in a recipe? (I assume registering the block is the same as normal too)
-
I've tried looking around Vanilla code for how to do this, but all the func_x everywhere started to get annoying. How does one add metadata to a block?
Edit:

In your GUIHandler.
Will try to fix this when I get home then. Would you happen to know why the buttons and whatnot don't show up? I just copied the Vanilla container.
-
You always pass
null
to the container as the villager.
You need to send the entityId with openGui (x, y, z are just integers, you dont have to use a location!) and then use world.getEntityById.
Where exactly do I use this world.getEntityById?

Hi,
I made my own GUI for a custom villager NPC I have. When I use the default GUI (same as Villager) the trader works perfectly. Whenever I put my own GUI in it's place, interacting crashes with this crash.
In my Entity class, if I move the drawing of the GUI outside of the !isRemote (which is no longer like Villager code) and into an isRemote, then I get to see the GUI except when I close it I get this crash (I don't see any of the GUI besides the main background part, there are no buttons, things he is selling, etc):

Ignore Invulnerability Period On Mobs
in Modder Support
Posted
How would I go about making a projectile ignore the moment when a mob turns red and goes invulnerable after being hit? This way my projectiles could hit them at a more rapid speed and still deal damage.
edit: If there is a way to remove the period on my mobs, that would work too.
