🛡️ 4-Point Input Interception Breakdown

When chat is hidden, ChatScreenMixin intercepts 4 critical input pathways to prevent background ghost typing or accidental link clicking:

Intercepted Method	Vanilla Behavior	Bed Chat Hider Action (When Hidden)	Result
extractRenderState	Renders chat background, history text, and command suggestions.	Invokes super.extractRenderState and executes ci.cancel().	Chat text and background box are completely invisible.
keyPressed	Types characters into input, autocompletes commands, cycles history.	Returns cir.setReturnValue(super.keyPressed(event)).	Typing and arrow cycling are disabled; Escape closes screen normally.
mouseClicked	Clicks chat text URLs, suggestions, or chat log selection.	Returns cir.setReturnValue(super.mouseClicked(event, doubleClick)).	Chat selection disabled; GUI buttons (Leave Bed, Show Chat) work cleanly.
mouseScrolled	Scrolls chat log history up and down.	Returns cir.setReturnValue(super.mouseScrolled(x, y, scrollX, scrollY)).	Log scrolling disabled; screen remains static.

💻 Source Code Verification

// Sourced from ChatScreenMixin.java
@Inject(method = "extractRenderState", at = @At("HEAD"), cancellable = true)
private void onExtractRenderState(GuiGraphicsExtractor graphics, int mouseX, int mouseY, float a, CallbackInfo ci) {
    if ((Object) this instanceof InBedChatScreen && BedChatHiderClient.hideChat) {
        super.extractRenderState(graphics, mouseX, mouseY, a);
        ci.cancel();
    }
}

@Inject(method = "keyPressed", at = @At("HEAD"), cancellable = true)
private void onKeyPressed(KeyEvent event, CallbackInfoReturnable<Boolean> cir) {
    if ((Object) this instanceof InBedChatScreen && BedChatHiderClient.hideChat) {
        cir.setReturnValue(super.keyPressed(event));
    }
}
