minecraft 1.8 gui slider issues - user-interface

Question

I recently started making a minecraft mod and i have a question regarding GUI's I want to create a slide, the only issue is the ButtonList.add(new GUISlider());
I don't understand the parameters, can someone explain them to me?
Thanks! :D

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 - 8) / 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 - 8);
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 - 8)), this.yPosition, 0, 66, 4, 20);
this.drawTexturedModalRect(this.xPosition + (int) (this.sliderValue * (float) (this.width - 8)) + 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 - 8);
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) {
this.dragging = false;
}
}
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, 8);
fontRendererObj.drawString("Train Name :", (int) (width / 2 - (width / 13)), (int) (height / 7.8), 8);
fontRendererObj.drawString("Max Speed :", (int) (width / 2 - (width / 13)), (int) (height / 3.5), 8);
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!
