I need some help please? Stop -1 coins to stay at 0

Question

I use a game engine called buildbox 3d.
I'm using JavaScript.
I'm trying to stop my coin value going past -1
If player has used all coins then I would like it to stay at zero until new coins have be given.

I can't seem to stop this -1 problem

Here's an example:

Function signal(name, value){
If(value){
Let amount = this.attribute('Amount');
This.scene().addScoreCoin('Amount');
} // This is the normal code then im trying to add
If(amount == 0);{
This.attribute('Amount');
This.active = false;
}
}
Any help would very much appreciated 👍👍

Answer 1

In the function where you check for the amount of coin hold by the player you should put a conditional statment that check if the coins are less then 0, if so then you set the amount of coin equal to zero!

Thank you Sekiro. I am leaning and hard to understand at the moment.
Could you provide an example for me please?
Thanks

Answer 3

Mmh I dont know how buildbox works so I cannot provide a real code, but in Javascript you would do something like this:
//variable that store coin amount
var coin = 100;
//now we need a function to check the amount of coin

function checkCoin()
{
if(coin < 0)
{
coin = 0;
}
}

so everytime the function checkCoin is called it will check if the coin amount is less the. 0 and if it is then it sets the coin amount back to 0!

Look this is a code I wrote sometime ago, at line 225 I do something similar, when player use 1 food to heal, he will get 10 health point, if player has 95 health point and will use 1 food, he will gain 10 health point so health will become 105! To stop that from happening I set a conditional to check when use food if life goes over 100 then life will be sets to 100 no matter what!
Basically the player has 95 healt, use 1 food gain 10 health, healt become 105 the function check health, health is greater then 100 so health will be set to 100 again.
Give a look at it maybe it will help you out:

From what I understand you need to do the same things, just check if coin are less then 0 instead of greater then 100!
