Builtins — UI Toolkit

A vector, theme-coloured immediate-mode widget library (HUD, meters, interface controls, game UI, plus a few faux-3D widgets). All widgets are drawn each frame; interactive ones read the mouse and return their state. Set the palette once with ui_theme; every widget takes an optional trailing r,g,b to override its main colour.

ui_theme(0,210,255,  60,255,180,  40,60,95,  255,90,90,  190,235,255,  10,16,24)

HUD / sci-fi overlays

ui_radar(cx,cy,r,sweep) · ui_compass(x,y,w,h,heading) · ui_reticle(cx,cy,r,spread) · ui_target(x,y,w,h,lock) · ui_panel(x,y,w,h,bevel) · ui_scanlines(x,y,w,h,density)

Meters & gauges

ui_bar(x,y,w,h,value,max) · ui_segbar(…,segs) · ui_gauge(cx,cy,r,value,max) · ui_ring(cx,cy,r,value,max) · ui_vu(x,y,w,h,levels_list) · ui_spark(x,y,w,h,values_list) · ui_battery(x,y,w,h,value,max)

Interface controls (interactive — return state)

ui_button(x,y,w,h) → 1 when clicked · ui_toggle(x,y,w,h,state) → new state · ui_slider(x,y,w,value,min,max) → new value · ui_checkbox(x,y,size,checked) → new checked · ui_tabs(x,y,w,h,count,active) → active index · ui_progress(x,y,w,h,frac) · ui_tooltip(x,y,w,h) · ui_stepper(x,y,w,h,value,step) → new value

Game UI

ui_healthbar(x,y,w,h,hp,max,pulse) · ui_cooldown(cx,cy,r,frac) · ui_counter(x,y,dw,dh,value,digits) (7-segment) · ui_minimap(x,y,w,h) · ui_dpad(cx,cy,r) → direction · ui_slotgrid(x,y,cols,rows,cell,sel) · ui_vignette(intensity, r,g,b)

Faux-3D in 2D space

ui_gauge3d(cx,cy,r,value,spin) · ui_panel3d(x,y,w,h,depth) · ui_radar3d(cx,cy,r,tilt,sweep)

Interface sounds

ui_sound("click"|"hover"|"confirm"|"error"|"toggle"|"tick") · audio_blip(freq,dur,wave,amp)
