This trigger takes an required nonnegative ID number as an argument. If the player's last projectile to make any kind of contact, made contact with the opponent and had the specified ID number, then ProjContactTime returns the number of ticks since that contact occurred. If the specified ID number is 0, then the projectile ID is not checked. If no projectile meets all the above conditions, then ProjContactTime returns -1.

Format: ProjContactTime(exprn)

Arguments:

- exprn (int) Expression evaluating to a nonnegative ID number.

Return type: int

Error conditions: Returns 'Bottom' if exprn evaluates to 'Bottom'. If a negative ID is specified, then the ID defaults to zero.

Example:

`trigger1 = ProjContactTime(1234) = 1
; Triggers if a projectile with ID 1234 just made contact with the opponent.
trigger1 = ProjContactTime(0) != -1 && ProjContactTime(0) < 15
; Triggers if any of the player's projectiles made successful contact with the opponent within the last 15 ticks.`
