🎮 Player Interaction Workflow

When a player enters a bed:

1. Minecraft opens InBedChatScreen.
2. By default in vanilla, a single wide Leave Bed button ($200\text{px}$ wide) sits at screen bottom.
3. Bed Chat Hider dynamically resizes the Leave Bed button to $98\text{px}$ and adds a matching $98\text{px}$ Hide Chat / Show Chat button next to it.
4. Clicking the toggle button flips the in-memory state, immediately refreshing all widgets without closing the screen or waking the player up.

📐 Coordinate Geometry & Split Math

Vanilla Minecraft calculates the single button position as: $$X_{\text{vanilla}} = \frac{W}{2} - 100, \quad \text{Width} = 200, \quad Y = H - 40$$

Bed Chat Hider decomposes this $200\text{px}$ span into a symmetrical dual-button cluster with a $4\text{px}$ center divide:

$$\text{Leave Bed Button: } X_1 = \frac{W}{2} - 100, \quad \text{Width}_1 = 98, \quad Y_1 = H - 40$$ $$\text{Center Gap: } \Delta X = 4\text{ px}$$ $$\text{Toggle Chat Button: } X_2 = \frac{W}{2} + 2, \quad \text{Width}_2 = 98, \quad Y_2 = H - 40$$

$$\text{Total Span: } W_1 + \Delta X + W_2 = 98 + 4 + 98 = 200\text{ px}$$

💻 Technical Code Implementation

// Sourced from InBedChatScreenMixin.java
@Inject(method = "init", at = @At("TAIL"))
private void onInit(CallbackInfo ci) {
    if (this.leaveBedButton != null) {
        this.leaveBedButton.setX(this.width / 2 - 100);
        this.leaveBedButton.setWidth(98);
    }

    Button toggleButton = Button.builder(
        bedchathider$getButtonMessage(),
        button -> {
            BedChatHiderClient.hideChat = !BedChatHiderClient.hideChat;
            this.rebuildWidgets();
        }
    ).bounds(this.width / 2 + 2, this.height - 40, 98, 20).build();

    this.addRenderableWidget(toggleButton);
    bedchathider$updateChatState();
}
