Sets the line activation flags of the line with the specified ID.

Parameters
  • lineid: The ID of the line of which to set the activation flags.
  • activation: The activation flags to set. Multiple flags can be set by using the bitwise OR operator (|) between the constant names:
    • SPAC_None — No flags.
    • SPAC_Cross — Activated when crossed by player.
    • SPAC_Use — Activated when used by player.
    • SPAC_MCross — Activated when crossed by monster.
    • SPAC_Impact — Activated when hit by projectile.
    • SPAC_Push — Activated when bumped by player.
    • SPAC_PCross — Activated crossed by projectile.
    • SPAC_UseThrough — Activated when used by player (with pass through).
    • SPAC_AnyCross — Activated by anything crossing it which does not have the TELEPORT.
    • SPAC_MUse — Activated by monsters using it.
    • SPAC_MPush — Activated by monsters bumping into it.
    • SPAC_UseBack — The line can be used from the back side.
  • repeat: Whether the line's assigned action special can be activated multiple times or not.

Equal to 0Can only be activated once

Examples

The following line sets the tagged line so it can be activated by bumping into it:

SetLineActivation(1, SPAC_PUSH);

Note that the above line also clears all other activation flags, if any, before setting the new flag. If adding a flag without clearing the ones which are already set is what is desired, then using GetLineActivation is needed:

SetLineActivation(1, GetLineActivation(1) | SPAC_PUSH);


This line clears all activation flags of the tagged line, if any:

SetLineActivation(1, SPAC_NONE);
