Editing the vertical size of the button in GUI

you can do this by locking the element but does your version have the image button option?

can you show your edits and what it looks like?

Oh yeah it will do that,

does your version have the undecorated option?

oh um,

it just works in newer versions, but I was going to say you could just fake it, not with the undecorated option. but just by making a black line texture and lining it up with the bottom of the button.

got this, i'm trying to port it to 1.15.2

👀

this looks so messy x3

so in the init method do something like this to the this.addButton

			int left_pos = this.guiLeft;
			int top_pos = this.guiTop;
			this.addButton(new Button(this.guiLeft + 56, this.guiTop + 51, 40, 10, "222", e -> {
				if (true) {
					SuperOldMod.PACKET_HANDLER.sendToServer(new ButtonPressedMessage(0, x, y, z));
					handleButtonAction(entity, 0, x, y, z);
				}
			}) {
				@Override
				public void render(int p_282682_, int p_281714_, float p_282542_) {
					super.render(p_282682_, p_281714_, p_282542_);
					
					ResourceLocation resourceLocation;
					if(this.isHovered()) {
						resourceLocation = new ResourceLocation("super_old:textures/button_hover.png");
					} else {
						resourceLocation = new ResourceLocation("super_old:textures/button.png");
					}
					RenderSystem.color4f(1, 1, 1, 1);
					RenderSystem.enableBlend();
					RenderSystem.defaultBlendFunc();
					Minecraft.getInstance().getTextureManager().bindTexture(resourceLocation);
					this.blit(this.x/*left_pos + 56*/, this.y/*top_pos + 51*/, 0, 0, this.width/*40*/, this.height/*10*/, this.width/*40*/, this.height/*10*/);
					RenderSystem.disableBlend();
				}
			});

Oh, which version did you switch to now? x3
