Used by the routine at CheckCharacterForRoomGraphics.
Fails the script unless the low three bits of IY+04 are set and IY+02 is above IX+02 by more than the object count of the value in A. A non-zero return means the script step succeeded.
|

| CombineCharacterRoom | DEE4 | LD B,A | Keep the value in A as the count. | |
|
None of the bits 07 are set in IY+04?
|
||||
| DEE5 | LD A,(IY+$04) | Return zero through ParseInputNumber_ReturnZero if none of the bits 07 are set in the byte at IY+04. | ||
| DEE8 | AND $07 | |||
| DEEA | JP Z,ParseInputNumber_ReturnZero | |||
| DEED | LD A,(IY+$02) | Go to CombineCharacterRoom_ClearResult if the byte at IY+02 is below the byte at IX+02. | ||

| DEFB | POP AF | |||
| DEFC | SUB B | |||
| DEFD | JR C,CombineCharacterRoom_ClearResult | |||

| DF17 | LD (IX+$0F),A | |||
| DF1A | LD B,A | |||
| DF1B | LD A,($A034) | Read the room display parameter, then call ProcessObjectLocationRecursively to run object location recursively. | ||
| DF1E | CALL ProcessObjectLocationRecursively | |||
| DF21 | OR %00000001 | Reset the zero flag. | ||
| DF23 | RET | Return. | ||
|
Reached through the display record at DF02, dispatched by DispatchLookedUpHandlerThird.
|
||||
| DF24 | LD A,($A034) | Pass the room display parameter in B and the room graphics parameter in A, and carry on at ProcessObjectAttribute_LookObjectRun. | ||

| DF34 | JR Z,CombineCharacterRoom_TestActionSucceeded | |||
| DF36 | LD HL,$A036 | Go to ParseInputNumber_ReturnZero if the containing object is not this character. | ||
| DF39 | CP (HL) | |||
| DF3A | JP NZ,ParseInputNumber_ReturnZero | |||
| CombineCharacterRoom_TestActionSucceeded | DF3D | OR %00000001 | Reset the zero flag. | |
| DF3F | RET | Return. | ||
| DF40 | DEFB $78,$10,$2E,$DF,$80,$40,$00,$00 | Display record read by ProcessDisplayRecord: flags 78 value 10 handler DF2E, parameters 80 40 00 00 00. | ||
