Nevermind! Thank you so much Ernio! You're such a talented programmer. Probably doesn't mean that much considering the circumstance of the issue but, the mod you're creating is incredible. Can't wait to see the beta!

@Ernio Thank you for that explanation! Honestly, even when messing with those variables; it doesn't change that damn left side. I'm probably missing the obvious so, I'll figure it out. @jabelar Honestly, it's not that complicated. I mean, your way is simpler but, the way coolAlias showed (the way I used) seems to work just fine. I don't see the point in adding them to a string array considering it is not needed.

Here's the initGui: public void initGui() { this.list = new GuiScrollingList(this.mc, this.width + 100, this.height, 0, this.height, -100, 14) { //MAKE THIS WORK! List players = mc.getNetHandler().playerInfoList; int selectedIndex = -1; protected boolean isSelected(int index) { if(index == selectedIndex) { return true; } return false; } protected int getSize() { return players.size(); } protected void elementClicked(int index, boolean doubleClick) { this.selectedIndex = index; this.isSelected(selectedIndex); } protected void drawSlot(int var1, int width, int height, int var4, Tessellator tess) { //mc.fontRenderer.setBidiFlag(true); for(int i = 0; i < getSize(); i++) { GuiPlayerInfo victim = ((GuiPlayerInfo)players.get(i)); mc.fontRenderer.drawString(victim.name, width / 2 - 20, height, 0xFFFFFF); } } protected void drawBackground() { } }; } What I mean is, every variable I change draws the left side way off screen. You can see this by the selection box that has no border for the left side.

So, I got the selection part to work but, there's no variable that I can change that allows me to bring in the left side. Check out the picture: http://i.imgur.com/vnCsneG.png

So, I got the player name to work by doing this in my draw slot method: for(int i = 0; i < getSize(); i++) { GuiPlayerInfo info = ((GuiPlayerInfo)players.get(i)); } So, that worked pretty well! But, I still can't figure out how to select an index. .-.

This is probably an idiotic question but, how exactly would I declare the index?

Ok so, I have this: this.list = new GuiScrollingList(this.mc, this.width + 100, this.height, 50, 150, -100, 24) { List players = mc.getNetHandler().playerInfoList; String[] strings = new String[]{"one", "two", "three"}; protected boolean isSelected(int index) { return false; } protected int getSize() { return players.size(); } protected void elementClicked(int index, boolean doubleClick) { this.isSelected(index); } protected void drawSlot(int var1, int width, int height, int var4, Tessellator tess) { //mc.fontRenderer.setBidiFlag(true); mc.fontRenderer.drawString(players.get(0).toString(), width / 3, height, 0xFFFFFF); } protected void drawBackground() { } }; All of it is declared in my initGui. Now a few questions, for starters; I can't seem to be able to select the text (Like with select world). To be honest, I looked through other classes and couldn't figure out how they did it. Secondly, how would I get the player username from the list? And thirdly, can I draw the scroll list over like a normal gui? What I mean is like the the background of the furnace gui or, does it require the whole screen to be overlayed?

I completely understand that. I have an understanding to where I can be giving a starting point and excel from there. This scrolling list is the only thing that has confused me from the start.

Oh and jabelar, I am not fully fluent in Java. I try my best to learn everything I can but, just like you may have experienced through your first years of programming; some things don't come as easy to me as others. But, I thank you for telling me what to look into in order to accomplish my goal.

Well thanks for the hints. I'll get to looking into creating it. I actually didn't know forge made a GuiScrollingList.

After viewing all those videos, not one showed how to screate a scrolling GUI. I would really appreciate some help on this matter. ;-;

Thank you for that but, it's not letting me view the lecture for the Interface tutorial.

See, I know it just is a thing that moves up and down but, when I look at the classes I get so confused. Someone really needs to right a tutorial explaining some of the key parts in implementing a scrolling type gui.

Thank you for that but, I still don't know how to add a scrolling Gui There's no real explanation for it. Also, couldn't you use "world.playerEntites"?

Ok so, I want to add to my gui a scrolling list containing the names of all the players on the server. But honestly, I have no clue how to accomplish this. If anyone can help that'd be great!

Well... that worked. I feel like the more difficult side of things when it comes to mod creation I understand and overcome. But the simplistic things I overlook and have to post a thread on it. Thanks to both of you.

I mainly just call "this.drawHoveringText()" from the GuiScreen class. Maybe they did something wrong?

I was just burned so hard.

Hey so, I made my gui and all that fancy stuff. But, when ever I display hovering text, this happens: http://i.imgur.com/l8NZpKU.png I really don't know what's causing this. I would really appreciate some help!

Maybe something like this? while(spellParalysis.isActive()) { KeyBoard.destroy(); Mouse.destroy(); } Not sure where you would put this but, I believe this disables the KeyBoard and Mouse.

I'm quite sure you can set an int to be the damage then set it as your tool material: int swordDamage = YourFormula; public static EnumToolMaterial DSRemake = EnumHelper.addToolMaterial("DSRemake", 0, 1000, swordDamge, 0, 0); Also, I suggest at least updating to 1.7 ESPECIALLY for your first mod. Considering 1.6 is no longer supported by forge and, the way everything is made has changed in 1.7; you'll be very confused when switching to 1.7.

I actually figured it out. After an hour, I found out by doing EntityPlayer player = (EntityPlayer)FMLCommonHandler.instance().getMinecraftServerInstance().getEntityWorld().getEntityByID(userID) I could get the EntityPlayerMP. To set the user id just do: int userID = Minecraft.getMinecraft().thePlayer.getEntityId(); Sorry for the pre-mature post! Didn't realize how persistent I could be.

I know the title is confusing but, basically I have a shop which is a GuiScreen. This GuiScreen opens when you right click the block (I have tried some things with the TileEntity to no avail). I really need to update the the coin amount or else it doesn't register. Any ideas?

Well, when I render it after the items are rendered, I get quite a weird lighting glitch and, the items still overlap.

Next time, please in case your code in "code" and "/code". It becomes quite difficult to read otherwise.
