-Xmx and -Xms parameters are being ignored (Forge Server).

Posted September 28, 201411 yr

I'm trying to run a forge server, and for some reason I can't allocate more RAM to it. I'm using a batch file with this command:

"C:\Program Files\Java\jre7\bin\java.exe" -Xms2048M -Xmx6144M -jar "forge-1.7.10-10.13.1.1217-universal.jar"

As you can see, I have 64 bit java, am running the latest Forge version, and have it set to use 2-6 GB of RAM. As far as I can tell I am doing nothing wrong.

However, whenever I start up forge it seems to be using far less RAM than I allocated. It seems to max out at 250 MB or so, and throws "java.lang.OutOfMemoryError: PermGen space" pretty frequently.

Can anyone help me out?

Ah what you're talking about is the Java heap space, -Xmx and -Xms are the values related to this.

Java is telling you you are out of PermGen space which is an entirely different parameter

add -XX:PermSize=256m in after your -Xmx and -Xms parameters, it should fix your problem

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
