For some reason.. I'm getting all kinds of errors from the servers, saying this

And yes, I have made my methods switch from server to client but it still doesn't work. Here is part of the entity file of where the problems occurs:

Since you've put the @SideOnly annotation on the method, it is not included as part of the class on the server. It will crash if you try to call it. Try replacing your particle code with this:

 

public void onLivingUpdate()
    {
        super.onLivingUpdate();
        if(FMLCommonHandler.instance().getEffectiveSide() == Side.CLIENT) spawnParticle();
        
    	for(int l = 0; l <= 4; ++l) //TODO
        {
    		 if(worldObj.rand.nextFloat() < footprint_chance) {
    			 continue;
    		 }
    		
            if(Constants.DEF_GRASSSTEP == true){
            	int x = MathHelper.floor_double(this.posX + (l % 2 * 2 - 1) * 0.25F);
            	int y = MathHelper.floor_double(this.posY) - 1 ;
            	int z = MathHelper.floor_double(this.posZ + (l / 2 % 2 * 2 - 1) * 0.25F);
            	BlockPos pos = new BlockPos(x, y, z);
            	IBlockState state = this.worldObj.getBlockState(pos);
            	boolean isAnyDirt = state.getBlock() == Blocks.dirt;
            	boolean isRegularDirt = isAnyDirt && state.getValue(BlockDirt.VARIANT) == BlockDirt.DirtType.DIRT;

You shouldn't use FMLCommonHandler to get the effective side when you have a World object available - if (worldObj.isRemote) is a much cheaper operation.

 

Whenever you have a method, class or field that operates on the client side only, you can only access it on the client side; i.e. any time you want to access it, nest your code in a side check:

if (worldObj.isRemote) { // yay, you're on the client
   spawnParticles(); // or other client-only code
}

None of these methods are working. Is it even possible to make custom particles spawn constantly as long as the entity lives?

When I move it over, it says the random is not public. Also it asks for to be static but with the random variables, it says it can't be static

@coolAlias: That alone will not work. It will still crash on a server.

A much better alternative to @SideOnly is @SidedProxy.

Are you sure? Because I've done just that in some of my mods and they play on servers just fine.

 

I understand that some things must be routed through the ClientProxy (the IMessageHandler getPlayer for example) because of the way classes load, but it seems such an inefficient solution.

 

Imagine that you have 20 entities and each one has a spawnParticles method, and within each the implementation is radically different. Do you create a special 'spawnParticles' method for each one in your ClientProxy? Do you create one method, but have chained if/elses checking if (entity instanceof EntityOne) spawnParticlesOne ? That would just be absurd.

 

Perhaps you could make an interface, ISpawnParticles, and cast your entity to that from the ClientProxy method which then calls the entity's class method, but it sounds like you are saying that would still crash since the actual implementation is within the entity class?

 

What a convoluted solution to what should be a simple problem, in my opinion. Granted, things don't always work the way we'd like, but this particular design decision (if it was a decision at all or just plain necessity) boggles my mind.

Hey now I have another problem releating to the client loading on the server side with a projectile entity. Here is it's class

 

public class EntityIceball extends EntityThrowable
{
    private static final String __OBFID = "CL_00001722";

    public EntityIceball(World p_i1773_1_)
    {
        super(p_i1773_1_);
    }

    public EntityIceball(World p_i1774_1_, EntityLivingBase p_i1774_2_)

    }
    
    @Override
    public void onUpdate()
    {
    	EntityIceDustFX var20 = new EntityIceDustFX(this.worldObj, this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D);
    	FMLClientHandler.instance().getClient().effectRenderer.addEffect(var20);
        
        super.onUpdate();
    }

    /**
     * Called when this EntityThrowable hits a block or entity.
     */
    protected void onImpact(MovingObjectPosition movingObject)
    {   
        if (movingObject.entityHit != null)
        {
            byte b0 = 0;

            if (movingObject.entityHit instanceof EntityBlaze)
            {
                b0 = 3;
            }

            movingObject.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)b0);
        }else{
        	
            BlockPos blockpos =  movingObject.getBlockPos().offset(movingObject.sideHit);

        	if (this.worldObj.isAirBlock(blockpos))
        	{
        		this.worldObj.setBlockState(blockpos, Blocks.ice.getDefaultState());
        	}
        }

        for (int i = 0; i < 8; ++i)

      Strange Crash Due to Error From Missing Class: net.minecraft.client.gui.screens.LoadingOverlay (Minecraft, Forge, 1.20.1)

      By Benjaggo · Posted

      I have been trying to solve a consistent crashing issue on my brother's computer where it will crash during the "Scanning Mod Candidates" phase of the loading process that starts when you click the play button on the Minecraft launcher. The issue seems to stem from a missing library that it mentions in the log file I provide below. I might I'm missing the bigger issue here for a smaller one but hopefully someone can find what I'm missing. Here's all of the stuff that I've been able to figure out so far: 1. It has nothing to do with mods, the crash happened with a real modpack, and even when I made a custom modpack and launched it without putting ANY mods into it (That is where the log file comes from by the way). 2. I have tried to find this class like a file in the Minecraft folders, but I've had no luck finding it (I don't think it works like that, but since I really don't understand how it works, I just figured I'd try). 3. I haven't seen anyone else have this issue before. 4. I know that my modpack (with mods) does work since I've run it on my computer, and it works fantastic. For some reason my brother's computer can't seem to run anything through curseforge. 5. This is for Minecraft version 1.20.1, Minecraft launcher version 3.4.50-2.1.3, forge 47.3.0, and curseforge app version 1.256.0.21056 6. My brother is using a Dell laptop from 6 years ago running Windows 10 (If you think more info on this would help, please ask as I do have it. I'm just choosing not to put it here for now). 7. I have reinstalled the curseforge app and installed Minecraft version 1.20.1. I have not reinstalled Minecraft or forge 47.3.0 but I didn't know if that would help. 8. I had an error code of 1 Please let me know if there is anything else that I am missing that you would like me to add to this post/add in a comment! Lastly, many thanks in advance to whoever can help! ------------- LOG FILE (latest.log) ------------- (from /Users/<NAME OF USER>/cursforge/minecraft/Instances/<THE NAME OF MY EMPTY MODPACK>/logs/latest.log) (This was made after running an empty modpack with same versions for all apps) ("[REDACTED]" is not the actual text from the log, it is me replacing text I figured wouldn't be necessary for fixing and would hurt my privacy) https://pastebin.com/hxXvGGEK ------------- DEBUG.LOG (I realized that I should have put this here first after I had done all of the work on putting latest.log in) -------------------- (again, "[REDACTED]" is not the actual text from the log, it is me replacing text I figured wouldn't be necessary for fixing and would hurt my privacy) https://pastebin.com/Fmh8GHYs
