Making a delay in method

[Rex_Technology]

So I want to create a delay in my method that destroys a block, waits for 20 ticks and then destroys the block below the destroyed one

Thank you

[ChampionAsh5357]

My recommendation is to make a capability which you can start a timer for a given block and destroy it once that timer has finished. It would probably be a list which you can tick that holds the block position and then calls the destroy block method in the level once it finishes.

Ok, thank you but how do I start the timer?

By calling a method in the capability you make to start it?

In java and in minecraft modding. I've learned java for minecraft modding.

[ChampionAsh5357]

I would suggest learning Java before modding. It's an absolutely terrible idea to learn it at the same time because Minecraft contains numerous bad practices and you are expected to have an intermediate level of Java knowledge beforehand since we do not explain Java concepts, only answer Minecraft related questions. It's like trying to run before figuring out how to stand.

I already learned java, I followed a java tutorial made by Kaupenjoe that is made for minecraft modding

Following a tutorial is not the same as learning a language, but your choice.

Regardless, I gave the answer above, use a capability on the level and create a timer method to handle the destroying. If you are using a block entity to destroy the block, then use that instead of a capability on the level. There are docs, wikis, and tutorials on capabilities if you are unsure of their system.

does a capabilities has an onTick() method

You need to make your own capability, and you can give it whatever methods you want.

well yes but not quite

short ago i have to made a capability extending itemhandler to make a custome drill and i need to recalculate the value of tick to calculate animation frame and fuel comsumtion but i cannot make it 

so i end quickitng an made just a 

	    public int get_tick() {
        if( this.tick > 0) {
        } 
        else if( this.action > 0) {
            if( this.start > 0L ) {
            //System.out.println( "Calcular_tick()\n" );
            this.tick = (int) ((System.currentTimeMillis() - this.start) / 50); // 50
            this.tick = (this.tick > this.limit)? this.limit : this.tick;
            }
        }        
        return this.tick;
    }
	

 

so everytime the code ask for that variable it recalculate it 

coze idont find any ontick() or public void tick()  that works inside the capability

Animation frame rendering can be lerped using the current tick data and the previous tick data. So, there's no 'not quite'. You can make an method and implement it like any other method in java.

[perromercenary00]

oo that 
when i made the animations using the tick provided by onUseTick 
causes chopping animations when the game start skiping frames 
an sometimes the animation locks in a cicle and dont let the item continue whit is normal use 

then i just begin to store the statr time as epoch and calculate the frame from it and fix the problem

Ok, so you're just calculating partial tick yourself instead of using the one provided by vanilla.

[perromercenary00]

if theres is a work around to make the logic inside the capability it would make things easier 
i try puting and onload method and launchi it from

i notice this methods ticks for a while afther you read the capability from the item and lives while the item is in the hotbar  but if you put it on the inventory and close the menu it dies so is not 

is not reliable becoze it only ticks a few times and stop so is unfited to make a long count and do something after like finishing the drilling action and consume the fuel value saving the numbers back to item 

the other option would be to call the capability once and again from the itemstack 
in older version there was a onupdate() method that constantly tick even when you toss the item into the world i dot find it in 1.19.2 surely the name has change
