## [area_create_warp_node](#area_create_warp_node)
### Description
Creates a warp node in the current level and area with id `id` that goes to the warp node `destNode` in level `destLevel` and area `destArea`, and attach it to the object `o`. To work properly, object `o` must be able to trigger a warp (for example, with interact type set to `INTERACT_WARP`.) `checkpoint` should be set only to WARP_NO_CHECKPOINT (0x00) or WARP_CHECKPOINT (0x80.) If `checkpoint` is set to `0x80`, Mario will warp directly to this node if he enters the level again (after a death for example)
