Hi, I was just wondering if there was a way of updating a string that is drawn in a gui without exiting the gui first. By update I mean change value if I have done something to make it change. I have made it so that it updates every time you exit the gui and open it again, but that is all I can do.

 

Here is the code I am using:

 

public class GuiReligion extends GuiScreen {

private int xSize = 176;

private int ySize = 166;

private String pantheon;

private String pantheonId;

EntityPlayer player;

public GuiReligion(EntityPlayer player) {

	this.player = player;
}

public void updateScreen() {
	super.updateScreen();

	pantheon = "Pantheon is set to " + ExtendedPlayer.get(player).getPantheon();
	pantheonId = "Pantheon ID = " + ExtendedPlayer.get(player).getPantheonId();
}

public void drawScreen(int x, int y, float f) {

	drawDefaultBackground();

	GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);

	mc.getTextureManager().bindTexture(Textures.GUI_RELIGION);

	int posX = (width - xSize) / 2;
	int posY = (height - ySize) / 2;

	drawTexturedModalRect(posX, posY, 0, 0, xSize, ySize);
	drawCenteredString(fontRendererObj, ExtendedPlayer.get(player).getPantheon(), posX + (xSize / 4 * 3), posY + 15, 0xffffffff);

	super.drawScreen(x, y, f);
}

public boolean doesGuiPauseGame() {

	return false;
}

@SuppressWarnings("unchecked")
public void initGui() {

	this.buttonList.clear();

	int posX = (width - xSize) / 2;
	int posY = (height - ySize) / 2;

	this.buttonList.add(new GuiButton(0, posX + 10, posY + 10, 50, 20, "None"));
	this.buttonList.add(new GuiButton(1, posX + 10, posY + 40, 50, 20, "Greek"));
	this.buttonList.add(new GuiButton(2, posX + 10, posY + 70, 50, 20, "Norse"));
	this.buttonList.add(new GuiButton(3, posX + 10, posY + 100, 50, 20, "Roman"));
	this.buttonList.add(new GuiButton(4, posX + 10, posY + 130, 50, 20, "Egyptian"));
}

public void actionPerformed(GuiButton button) {

	switch (button.id) {
		case 0:
			ItemTalisman.pantheon = 1;
			pantheon = "None";
			pantheonId = "" + 1;
			System.out.println(pantheon);
			System.out.println(pantheonId);
			break;
		case 1:
			ItemTalisman.pantheon = 2;
			pantheon = "Greek";
			pantheonId = "" + 2;
			System.out.println(pantheon);
			System.out.println(pantheonId);
			break;
		case 2:
			ItemTalisman.pantheon = 3;
			pantheon = "Norse";
			pantheonId = "" + 3;
			System.out.println(pantheon);
			System.out.println(pantheonId);
			break;
		case 3:
			ItemTalisman.pantheon = 4;
			pantheon = "Roman";
			pantheonId = "" + 4;
			System.out.println(pantheon);
			System.out.println(pantheonId);
			break;
		case 4:
			ItemTalisman.pantheon = 5;
			pantheon = "Egyptian";
			pantheonId = "" + 5;
			System.out.println(pantheon);
			System.out.println(pantheonId);
			break;
	}
}
}

 

I don't know much about gui's but I think if you look at the furnaces progress bar I think you could implement that in a way so that the text changes.

If I understand the code correctly that won't work because they are not really using a variable that shows up, but they are rendering a square that get's bigger and bigger. Rendering that should go fine, but I think variables need an update.

public void updateScreen() {

super.updateScreen();

 

pantheon = "Pantheon is set to " + ExtendedPlayer.get(player).getPantheon();

pantheonId = "Pantheon ID = " + ExtendedPlayer.get(player).getPantheonId();

}

this is the method that is called on exiting the screen right?

public void updateScreen() {

super.updateScreen();

 

pantheon = "Pantheon is set to " + ExtendedPlayer.get(player).getPantheon();

pantheonId = "Pantheon ID = " + ExtendedPlayer.get(player).getPantheonId();

}

That might be possible.

Try calling it from another class to check if it works while the gui is open.

I tried calling it from the onItemRightClick method in one of my item classes. Seems like the code inside there is reachable even when it's opened.

public void actionPerformed(GuiButton button) {

what if you add it to all the cases in side this and add a System.out.println to check if it is called ?

public void actionPerformed(GuiButton button) {

Doesn't help any

damn well sorry but I'm out of options haha :3

That code only fires when a GuiButton is pressed. You should probably use the drawGuiForegroundLayer method to draw the strings, because that's updated every tick.

Yeah that was to check if anything happens with that method once he clicks the button...

This would work if I had a class that extends GuiContainer, but I am extending GuiScreen which has no such method.

Sorry, it was just I that was dumb. It was something else that caused it not to update. It had nothing to do with the code I used in there.
