| The only drawing functions in HUD Library are [[functions:HudDrawText]] and [[functions:HudDrawImage]]. They call [[zdoom>SetHudSize]], [[zdoom>SetFont]] and then HudMessage(Bold) every time a message is drawn. This means that if you are mixing HUD Library with HudMesasge, then, after calling one of HudDraw* functions, your SetHudSize and SetFont settings are lost and you need to set them back. | The only drawing functions in HUD Library are [[functions:HudDrawText]] and [[functions:HudDrawImage]].

| The whole [[HUD Library state]] can be reset to default using [[function:HudResetState]]. It can be saved and loaded using [[function:HudPushState]] and [[function:HudLoadState]] to a stack. The stack's maximum size is defined in [[ACSUtils_configuration#ACSUTILS_HUDLIB_SAVEDSTATES|ACSUTILS_HUDLIB_SAVEDSTATES]] ACSUtils setting.
