| | | K. MOVEMENT TYPES |
| | | ============================================================ |
| | | |
| | | The movement types (MOVE_..) is a bitmask that determines which method |
| | | of locomotion the object is using, and is also used to determine what |
| | | types of movement the space blocks. From define.h: |
| | | |
| | | #define MOVE_WALK 0x1 /* Object walks */ |
| | | #define MOVE_FLY_LOW 0x2 /* Low flying object */ |
| | | #define MOVE_FLY_HIGH 0x4 /* High flying object */ |
| | | #define MOVE_SWIM 0x8 /* Swimming object */ |
| | | |
| | | The fields in the object themselves: |
| | | |
| | | move_type: Bitmask of above values which determines what form of movement |
| | | this object uses. For objects equipped by player/monster, move_type grants |
| | | that movement. |
| | | |
| | | Note that move_type of MOVE_FLY (0x2) replaces FLAG_FLYING. |
| | | |
| | | In general, creatures will only have 1 movement type active at a time. |
| | | |
| | | move_block: Represents what movement types are unable to pass this space. |
| | | If the creature has multiple movement types, they may still be able |
| | | to pass the space. For example, a player has MOVE_WALK | MOVE_FLY. |
| | | He tries to move onto a space that blocks MOVE_WALK - not a problem, |
| | | a he just flies over. |
| | | |
| | | move_on/move_off: Take bitmasks - represents for what movement types |
| | | this object is activated on. Replaces the walk/fly_on/off values |
| | | |
| | | move_slow: Like move_block, but represents what movement types are slowed |
| | | on this space. Note that it is not possible to specifiy different |
| | | penalties for different movement types in the same object. However, |
| | | multiple objects with different move_slow values (and penalties) can |
| | | be put on the same space. This replaced FLAG_SLOW_MOVE, which is |
| | | converted to only slow down walking movement |
| | | |
| | | move_slow_penalty (was slow_move) - how much the player is slowed down. |
| | | This value is a float (before it was an int converted to a float |
| | | at load time). It is basically how much slower (percentage wise) |
| | | the player moves through this terrain. A value of 0 is basically |
| | | a non operation. A value of 0.5 means it takes 50% longer to move |
| | | through the space. |
| | | |
| | | Certain terrain has skills which reduce the slow penalty (woodsmen |
| | | in forest for example). As of this writing, the penalty is reduced |
| | | to 1/4 of what it would be. Eg, a move_slow_penalty of 1.0 would |
| | | say it takes twice as long to move through the space. If the player |
| | | has appropriate skill, it would now only take that player 25% |
| | | longer to move through the space. |
| | | |
| | | move_state/move_status: This is unrelated to this movement code - it is |
| | | used for monster attack_movement information. it is only noted here |
| | | since it starts with the move_ prefix. |
| | | |
| | | msg/endmsg: If an object has move_block of move_slow and that affects |
| | | the player movement, the objects message will be printed to the player - |
| | | thus things like 'The jungle slows you down' or 'The wall is in the way' |
| | | will be printed. Various hints can be contained in the messages. |
| | | |
| | | Load/Save behaviour and backward compatability: |
| | | The loader knows about certain old flags (walk_on, blocked, etc) and |
| | | sets up the appropriate bitmasks. When data is saved, it is saved |
| | | as the move_... with actual bitmasks. |
| | | |
| | | Special player notes: |
| | | Player can only pick up items if MOVE_WALK is set (this may need |
| | | to be expanded down the road). Basic idea is that if you are flying, |
| | | can't reach the ground, if swimming, don't really have any free hands |
| | | to grab anything. |
