Linedef type 307

From SRB2 Wiki
Jump to: navigation, search

Linedef type 307, Character Ability - Once, is a type of linedef executor trigger which activates any linedef executor in the control sector when a player with a specific character ability activates a tagged trigger sector. Unlike linedef type 305, this linedef executor will trigger only the first time, and then cannot be triggered again until the map is reloaded.

Setup

The length of the controlling linedef determines which characters with specific abilities can trigger the linedef executor, as shown in the table below:

Length Ability
0-9 No ability
10-19 Thok
20-29 Flying
30-39 Gliding and climbing
40-49 Homing attack
50-59 Swimming
60-69 Double jump
70-79 Floating
80-89 Floating with slow descent
90-99 Telekinesis
100-109 Fall switch
110-119 Jump boost
120-129 Air drill
130-139 Jump-thok

Note that due to a bug in the current version of SRB2, the effect of the trigger is inverted: All characters except those with the specified ability can activate the trigger.
