Hello,
I'm pretty new at developing forge mods and wanted to use my own fonts for titles etc for the main menu. I created my own FontRenderer and overwrote the renderUnicodeChar method there, but the text still looks pretty strange.

 

The custom class:

import net.minecraft.client.gui.FontRenderer;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.client.renderer.texture.TextureManager;
import net.minecraft.client.settings.GameSettings;
import net.minecraft.util.ResourceLocation;

public class CustomFontRenderer extends FontRenderer {

    public CustomFontRenderer(GameSettings gameSettingsIn, ResourceLocation location, TextureManager textureManagerIn, boolean unicode) {
        super(gameSettingsIn, location, textureManagerIn, unicode);
    }

    @Override
    protected float renderUnicodeChar(char ch, boolean italic) {
        int i = this.glyphWidth[ch] & 255;

        if (i == 0) {
            return 0.0F;
        } else {
            this.bindTexture(locationFontTexture);
            int k = i >>> 4;
            int l = i & 15;
            float f = (float) k;
            float f1 = (float) (l + 1);
            float f2 = (float) (ch % 16 * 16) + f;
            float f3 = (float) ((ch & 255) / 16 * 16);
            float f4 = f1 - f - 0.02F;
            float f5 = italic ? 1.0F : 0.0F;
            GlStateManager.glBegin(5);
            GlStateManager.glTexCoord2f(f2 / 256.0F, f3 / 256.0F);
            GlStateManager.glVertex3f(this.posX + f5, this.posY, 0.0F);
            GlStateManager.glTexCoord2f(f2 / 256.0F, (f3 + 15.98F) / 256.0F);
            GlStateManager.glVertex3f(this.posX - f5, this.posY + 7.99F, 0.0F);
            GlStateManager.glTexCoord2f((f2 + f4) / 256.0F, f3 / 256.0F);
            GlStateManager.glVertex3f(this.posX + f4 / 2.0F + f5, this.posY, 0.0F);
            GlStateManager.glTexCoord2f((f2 + f4) / 256.0F, (f3 + 15.98F) / 256.0F);
            GlStateManager.glVertex3f(this.posX + f4 / 2.0F - f5, this.posY + 7.99F, 0.0F);
            GlStateManager.glEnd();
            return (f1 - f) / 2.0F + 1.0F;
        }
    }
    
}

 

Preview of the custom font.

 

I initialized the renderer as follows:

 

FontRenderer fontrenderer = new CustomFontRenderer(mc.gameSettings, new ResourceLocation("mountainmod", "textures/font/cammron/ascii.png"), mc.renderEngine, true);

 

My idea where the problem is is the size / resolution of the ascii.png. The ascii.png of Minecraft is 128x128 pixel large, the ascii.png of my font(s) is 1024x1024 pixels or 2048x2048 pixels large (I tried 2 fonts).

 

 

Best regards.

I think it’s probably the game resolution being too small to render all the pixels of your font, what does it look like in full screen?

I had Minecraft in window mode at full size at 1080p. I also had it smaller, but nothing changed, so I don't think the resolution is the rendering problem. Maybe I'm wrong...
