I recently started working on a mod and I ran into a GUI problem, I can;t figure out how to get a slider in my GUI, many things online say to use a controlList but I says its not there when i use this.controlList.add(); So can someone give me a slider code and how to get it working.  Thanks!

Its is very easy. Create a new variable of ty GuiSlider - Just add it to the buttonList and in the onMouseClicked method, put in Yourvariable.onMouseClicked();

ok i get that, but  can you ellaborate on what to put, I can't figure out what goes where in all the parameters

Just hover over the new GuiSlider and it will show up a box with the needed arguments. And if not do ctrl and click on GuiSlider. It will bring up the class and you can read it.

ok, I figured it out, you need to create a separate slider other than the default, then call it from there.

 

My Slider Code:

 

package tutorial.generic;

 

import net.minecraft.client.Minecraft;

import net.minecraft.client.gui.FontRenderer;

import net.minecraft.client.gui.GuiButton;

import net.minecraft.client.renderer.GlStateManager;

 

import org.lwjgl.opengl.GL11;

 

public class GuiSliderFixed extends GuiButton {

 

public float sliderValue = 1.0F;

public float sliderMaxValue = 1.0F;

public float sliderMinValue = 1.0F;

public boolean dragging = false;

public String label;

 

public GuiSliderFixed(int id, int x, int y, String label, float startingValue, float maxValue, float minValue) {

    super(id, x, y, 150, 20, label);

    this.label = label;

    this.sliderValue = startingValue;

    this.sliderMaxValue = maxValue;

    this.sliderMinValue = minValue;

}

 

protected int getHoverState(boolean par1) {

    return 0;

}

 

 

@Override

public void drawButton(Minecraft mc, int mouseX, int mouseY)

{

    if (this.visible)

    {

        FontRenderer fontrenderer = mc.fontRendererObj;

        mc.getTextureManager().bindTexture(buttonTextures);

        GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

        this.hovered = mouseX >= this.xPosition && mouseY >= this.yPosition && mouseX < this.xPosition + this.width && mouseY < this.yPosition + this.height;

        int k = this.getHoverState(this.hovered);

        GlStateManager.enableBlend();

        GlStateManager.tryBlendFuncSeparate(770, 771, 1, 0);

        GlStateManager.blendFunc(770, 771);

        this.drawTexturedModalRect(this.xPosition, this.yPosition, 0, 46 + k * 20, this.width / 2, this.height);

        this.drawTexturedModalRect(this.xPosition + this.width / 2, this.yPosition, 200 - this.width / 2, 46 + k * 20, this.width / 2, this.height);

        this.mouseDragged(mc, mouseX, mouseY);

        int l = 14737632;

 

        if (packedFGColour != 0)

        {

            l = packedFGColour;

        }

        else if (!this.enabled)

        {

            l = 10526880;

        }

        else if (this.hovered)

        {

            l = 16777120;

        }

 

        this.drawCenteredString(fontrenderer, this.displayString, this.xPosition + this.width / 2, this.yPosition + (this.height - / 2, l);

    }

}

 

protected void mouseDragged(Minecraft par1Minecraft, int par2, int par3) {

    if (this.enabled && this.visible && this.packedFGColour == 0) {

        if (this.dragging) {

            this.sliderValue = (float) (par2 - (this.xPosition + 4)) / (float) (this.width - ;

 

            if (this.sliderValue < 0.0F) {

                this.sliderValue = 0.0F;

            }

 

            if (this.sliderValue > 1.0F) {

                this.sliderValue = 1.0F;

            }

 

        }

 

        this.displayString = label + ": " + (int) (sliderValue * sliderMaxValue);

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

        this.drawTexturedModalRect(this.xPosition + (int) (this.sliderValue * (float) (this.width - ), this.yPosition, 0, 66, 4, 20);

        this.drawTexturedModalRect(this.xPosition + (int) (this.sliderValue * (float) (this.width - ) + 4, this.yPosition, 196, 66, 4, 20);

    }

}

 

public boolean mousePressed(Minecraft par1Minecraft, int par2, int par3) {

    if (super.mousePressed(par1Minecraft, par2, par3)) {

        this.sliderValue = (float) (par2 - (this.xPosition + 4)) / (float) (this.width - ;

 

        if (this.sliderValue < 0.0F) {

            this.sliderValue = 0.0F;

        }

 

        if (this.sliderValue > 1.0F) {

            this.sliderValue = 1.0F;

        }

 

        this.dragging = true;

        return true;

    } else {

        return false;

    }

}

 

public void mouseReleased(int par1, int par2) {

}

}

My GUI Code:

 

package tutorial.generic;

 

import java.awt.Color;

import java.io.IOException;

 

import net.minecraft.client.gui.GuiButton;

import net.minecraft.client.gui.GuiScreen;

import net.minecraft.client.gui.GuiSlider;

import net.minecraft.client.gui.GuiTextField;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.nbt.NBTTagCompound;

import net.minecraft.util.ChatComponentText;

import net.minecraft.util.ResourceLocation;

import net.minecraft.util.StatCollector;

import net.minecraft.world.World;

 

public class guiGenericTileEntity extends GuiScreen{

 

public static NBTTagCompound nameTag = new NBTTagCompound();

private int x, y, z;

private EntityPlayer player;

private World world;

private int xSize, ySize;

public static GuiTextField textField;

public static GuiSliderFixed mySlider;

public static NBTTagCompound maxSpeedTag = new NBTTagCompound();

public guiGenericTileEntity(EntityPlayer player, World world, int x, int y, int z) {

 

    this.x = x;

    this.y = y;

    this.z = z;

    this.player = player;

    this.world = world;

    xSize = 176;

    ySize = 214;

}

 

 

 

private ResourceLocation backgroundimage = new ResourceLocation(Generic.MODID.toLowerCase() + ":" + "textures/gui/guiBackGenericTileEntity.png");

 

@Override

public void drawScreen(int mouseX, int mouseY, float renderPartialTicks) {

    this.mc.getTextureManager().bindTexture(backgroundimage);

    int x = (this.width - xSize) / 2;

    int y = (this.height - ySize) / 2;

    drawTexturedModalRect(x, y, 0, 0, xSize,  ySize);

 

    fontRendererObj.drawString("MTTA System", (int) (width / 2 - (width / 13)), height / 15, ;

    fontRendererObj.drawString("Train Name :", (int) (width / 2 - (width / 13)), (int) (height / 7., ;

    fontRendererObj.drawString("Max Speed :", (int) (width / 2 - (width / 13)), (int) (height / 3.5), ;

 

 

 

    textField.drawTextBox();

 

    super.drawScreen(mouseX, mouseY, renderPartialTicks);

}

 

@Override

public boolean doesGuiPauseGame() {

    return false;

}

 

@Override

public void updateScreen(){

    textField.updateCursorCounter();

 

    super.updateScreen();

}

 

@Override

protected void keyTyped(char typedChar, int keyCode) throws IOException{

    textField.textboxKeyTyped(typedChar, keyCode);

    super.keyTyped(typedChar, keyCode);

}

 

@Override

public void initGui(){

 

 

    buttonList.add(new GuiButton(1, (int) (xSize / 3 * 2.35), ySize - (ySize / 18), xSize - 20, height / 12, "Save And Close"));

 

    mySlider = new GuiSliderFixed(3, width / 2 - 75, height / 3, "MPH ", 1.0F, 100.0F, 1.0F);

    buttonList.add(mySlider);

    mySlider.sliderValue = maxSpeedTag.getFloat("MaxSpeed");

 

    textField = new GuiTextField(width / 2, fontRendererObj, width / 2 - 50, (int) (height /  6), 100, 20);

    textField.setMaxStringLength(30);

    textField.setText(nameTag.getString("Name"));

    textField.setFocused(true);

    textField.setCanLoseFocus(false);

    super.initGui();

}

 

@Override

protected void actionPerformed(GuiButton guibutton) {

    //id is the id you give your button

    switch(guibutton.id) {

    case 1:

        player.closeScreen();

        nameTag.setString("Name", textField.getText());

        maxSpeedTag.setFloat("MaxSpeed", mySlider.sliderValue);

        genericTileEntity.processActivate(player, world);

        player.addChatMessage(new ChatComponentText("Saved the current settings for " + textField.getText() + "!"));

        break;

    }

    //Packet code here

    //PacketDispatcher.sendPacketToServer(packet); //send packet

}

 

 

 

 

 

}

Calling the new Slider works like this:

 

create a new GuiSliderFixed in the GUI code ---> example: ---> GuiSliderFixed mySlider = new GuiSliderFixed();

 

set the Parameters to this (int id, int x, int y, String label, float statingValue, float maxValue, float minValue) ---> example: ---> GuiSliderFixed mySlider = new GuiSliderFixed(3, width / 2 - 75, height / 3, "MPH ", 1.0F, 100.0F, 1.0F);

 

add it to buttonList ---> example ---> buttonList.add(mySlider);

 

Hope This Helps!

Uhm, you don't need to create a new GuiSlider class. This is unnessecary! Just make a new GuiSlider variable and define it as new GuiSlider();

add it to the buttonList and don't forget to update it and add it to the onMouseClicked method. This is all you need.
