[1.9.4] Help with Reflections needed, it always catches an exception

[Tomson124]

Hey everyone,

 

I am currently in the process of updating a mod to 1.9.4 and I try to get rid of the Access Transformer, so I tried to get the variable with a Reflection but everytime I do "getInt" to the field it just catches an exception.

 

int i;

public ClientTickHandler() {
	try {
		sprintToggleTimer = ReflectionHelper.findField(EntityPlayerSP.class,  "sprintToggleTimer", "field_71156_d");
		i = sprintToggleTimer.getInt(mc.thePlayer);

	}

	catch (Exception e) {
		SimplyJetpacks.logger.error("Unable to find field \"sprintToggleTimer\"");
	}
	System.out.println("i = " + i);
}

 

Hope someone can help me

The one I had defined: "Unable to find field sprintToggleTimer"

That's not the actual exception.  You have this:

catch (Exception e) {

 

This is known as a Pokemon Catch Block.  I.e. "gotta catch em all!"

 

You didn't even then print out the error but instead a generic "I had a problem" message.

Where are you creating an instance of ClientTickHandler? I'm assuming you do it in one of the initialization states (pre-init probably), which means mc.thePlayer will be null. You can fetch the field from EntityPlayerSP in your constructor, but you cannot read it while not in-game.

So the error is just with my "debug" integer i... I see...

The weird thing is that the exception is not caught ingame but it is not working like I supposed it to be either.

 

if(!sprintKeyCheck && sprintToggleTimer != null && mc.thePlayer.movementInput.moveForward >= 1.0F && !mc.thePlayer.isCollidedHorizontally && (mc.thePlayer.getFoodStats().getFoodLevel() > 6.0F || mc.thePlayer.capabilities.allowFlying))
	{
		if (sprintToggleTimer.getInt(mc.thePlayer) <= 0 && !mc.gameSettings.keyBindSprint.isKeyDown()) {
			sprintToggleTimer.setInt(mc.thePlayer, 7);
                sprintKeyCheck = true;
            }

		mc.thePlayer.setSprinting(true);
	}

 

This (coupled with some other methodes) should make it possible to sprint in midair with the jetpack to activate its boost, but as a result I am always sprinting as soon as I am not on the ground which is not what should happen

Okay I figured it out was just a really dumb mistake... I just forgot the "else" after the "if" 

But thanks everyone for the help
