Hello, I'm looking for a way to check, if player's current X(or any axis really) ends with .99 and then fire an event.

My current code:

double playerX = Math.floor(Minecraft.getMinecraft().thePlayer.posX);
        double playerY = Math.floor(Minecraft.getMinecraft().thePlayer.posY);
        double playerZ = Math.floor(Minecraft.getMinecraft().thePlayer.posZ);
        double playerYaw = Minecraft.getMinecraft().thePlayer.rotationYaw;

if (String.format("%.2f", playerX) = endsWith(.99));
        {
            LogHelper.info("true");
        }

First:

double playerX = Math.floor(Minecraft.getMinecraft().thePlayer.posX);

The floor function maps a number to its largest preceeding integer (e.g. 29.99 -> 29.00), so you will have a value ending with .00.

 

Second:

if (coordinate > 0) {
    float v = coordinate - .99;
    if (x = (int) x) {
        // the player's positive coordinate ends with .99
    }
} else {
    float v = coordinate + .99;
    if (x = (int) x) {
        // the player's negative coordinate ends with .99
    }
}

 

Note: if the coordinates have more than two digits after the decimal point, this code will mess up. If that is the case, be sure to truncate the floats.

Hi

 

I think your sample code will work fine with a bit of tweaking

    
double playerXfloor = Math.floor(Minecraft.getMinecraft().thePlayer.posX);
double playerXremainder = Minecraft.getMinecraft().thePlayer.posX - playerXfloor;
    if (String.format("%.2f", playerXremainder ).contains(".99"));
    {
      LogHelper.info("true");
    }

For positive numbers, this will trigger for any numbers between x.985 and x.9949999999

For negative numbers, this will trigger at numbers ending in 0.01 instead of 0.99

 

Is that what you want?

 

I'm with DieSieben though, are you sure that's really the effect you're looking for?

Then I don't think you want to check "ends with .99". I think you want to check "first two decimal places are 99".

Then it's all just maths:

 

double absPos = Math.abs(player.posX);
boolean endsWith99 = (int) ((absPos - (int) absPos) * 100) == 99;

 

 

Alright, I had to make it check for just 9 and add booleans for 8 and 7, but it works and does exactly what I want.

Thank you very much!
