Drop Point Marker Description This is a special type of Event which doesn’t respond to On or Off messages. This Event is used as a position where AI will drop off objects while in AI_COLLECTING_MODE. This is how Grabber robots can drop their rocks off at a specific location.

Explode Description This Event will cause an explosion to occur at the Event location. The explosion can be made to cause a geomod, and you can control the amount of damage caused by the explosion.

On Response Make the explosion happen.

Off Response None.

Parameters Damage: The amount of damage caused by the explosion. This is the damage that is applied to any object within the explosion range.

Type: Small, Medium, Large. This field isn’t properly supported yet. We need to list a selection of different explosions to choose from.

Geomod: If true, the explosion will apply a geomod at the center of the explosion. The hardness of the rock where the explosion occurs is used to determine if a geomod is possible.

Always Face Player: If true, the AI will always face the player while following their waypoints

Max Speed Scale (0-100): Used to make the AI move slower while following waypoints

Follow Method: This determines how the AI will behave when the last waypoint node is reached. The choices are: 1. One way: follow the waypoints to the last node and stop. 2. Loop: follow the waypoints to the last node, then return to the start and repeat 3. Ping Pong: follow the waypoints to the last node, then follow the nodes back to the start (repeat).
