[1.11] [Client-Mod] Gui word wrap

[SHsuperCM]

Ok, so I have GuiQuestBook.class that has some information in it like quests' names, levels, difficulty etc..

What it also has is a description that changes while doing the quest(it tells usally what to do),

The problem is, the gui has a texture which is limited in size and some of the descriptions go beyond the texture.

So, as the title might suggest, I'm trying to do a word wrap to keep the description within the texture.

I've tried looking for ways to do it but found nothing that works..

One thing to keep in mind is that im scaling the text also using GL so I need it to work with any scale multiplier, I wrote this method on my GuiScreen extension:

public void drawString(FontRenderer fontRendererIn, String text, int x, int y, float size, int color) {
        GL11.glScalef(size,size,size);
        float mSize = (float)Math.pow(size,-1);
        this.drawString(fontRendererIn,text,x,y,color);
        GL11.glScalef(mSize,mSize,mSize);
}

The width I'm aiming for with this is 225 pxls and the scale size I'm using is 0.9f btw..

You should be able to use FontRenderer#drawSplitString or FontRenderer#listFormattedStringToWidth for this.

Ok, so I wrote this:

public void drawSplitString(FontRenderer fontRenderer, String str, int x, int y, int wrapWidth, float size, int textColor)
    {
        GL11.glScalef(size,size,size);
        float mSize = (float)Math.pow(size,-1);
        fontRenderer.drawSplitString(str,x,y,wrapWidth,textColor);
        GL11.glScalef(mSize,mSize,mSize);
    }

inside the GuiScreen extension and put in GuiQuestBook this:

this.drawSplitString(mc.fontRendererObj,showedQuest.getQuestDescription(),(this.width / 2) - 102,160,225,0.9f,Integer.parseInt("FFFFFF",16));

and it produced:

Any ideas on how to fix it?

 

EDIT, for some reason refreshing made up this:

and now the text looks wierd..

I'm not too sure, sorry. I don't know all that much about rendering.

It's ok, I think I'm on to something, testing now and will post here the solution for anyone that needs..

Yay! finally figured it!

If anyone needs:

public void drawString(FontRenderer fontRendererIn, String text, int x, int y, float size, int color) {
        GL11.glScalef(size,size,size);
        float mSize = (float)Math.pow(size,-1);
        this.drawString(fontRendererIn,text,x,y,color);
        GL11.glScalef(mSize,mSize,mSize);
    }

public void drawSplitString(FontRenderer fontRenderer, String str, int x, int y, int wrapWidth, float size, float padding, int textColor)
    {
        GL11.glScalef(size,size,size);
        float mSize = (float)Math.pow(size,-1);

        int i = 0;
        for (String string:fontRenderer.listFormattedStringToWidth(str,wrapWidth)) {
            drawString(fontRenderer,string,x,y + Math.round(i * size * fontRenderer.FONT_HEIGHT * padding),size,textColor);
            i++;
        }

        GL11.glScalef(mSize,mSize,mSize);
    }

Also, Tnx  @Choonster for showing me FontRenderer#listFormattedStringToWidth, it helped alot!
