TypoShooter Mode Text Input Field Rendering¶

Summary¶

The implementation in src/crimson/modes/typo_mode.py now matches the original game's rendering. The original uses a custom rendering path in typo_gameplay_update_and_render (for Typ-o-Shooter mode), not the standardized ui_text_input_update function.

Current Implementation Status: ✅ FIXED¶

The implementation now correctly matches the original at 0x004457C0:

Constants (lines 36-43)¶

TYPING_PANEL_WIDTH = 182.0      # Original: 182.0
TYPING_PANEL_HEIGHT = 53.0      # Original: 53.0
TYPING_PANEL_ALPHA = 0.7        # Original: 0.7
TYPING_TEXT_X = 6.0             # Original: 6.0
TYPING_PROMPT = "> "            # Original: part of format string
TYPING_CURSOR = "_"             # Original: DAT_004712b8 = "_"
TYPING_CURSOR_X_OFFSET = 14.0   # Original: text_width + 14.0

Rendering Sequence (_draw_typing_box)¶

1. Panel Backdrop
2. Texture: ind_panel (original: DAT_0048f7c4 = ui/ui_indPanel.jaz)
3. Position: x=-1.0, y=screen_height - 144.0
4. Size: 182.0 × 53.0
5. Alpha: 0.7

6. UV: Full texture (0.0, 0.0, 1.0, 1.0) - simple stretch, no 9-slice

7. Typing Text

8. Position: x=6.0, y=screen_height - 127.0
9. Format: "> " + text (prompt + user input)
10. Color: White (255, 255, 255, 255)

11. Uses _draw_ui_text (equivalent to grim_draw_text_small_fmt)

12. Cursor

13. Character: "_" (underscore) from DAT_004712b8
14. Alpha: sin(t * 4.0) > 0.0 ? 1.0 : 0.4
15. Position: x = 6.0 + prompt_width + text_width + 14.0, y=screen_height - 127.0

Positioning Details¶

From the decompiled code at 0x004457C0:

v38 = config_screen_height - 128.0;     // Base Y position

// Panel drawn at:
//   x = -1.0
//   y = v38 - 16.0 = screen_height - 144.0

// Text drawn at:
//   x = 6.0
//   y = v38 + 1.0 = screen_height - 127.0

// Cursor drawn at:
//   x = text_width + 14.0
//   y = same as text (v38 + 1.0)

The text is vertically centered within the panel (17 pixels from top of 53-pixel panel).
