GMSCollisionBehaviorRequired (Varsayılan): Çakışma olup olmadığına bakılmaksızın işaretçiyi her zaman gösterir. Bu, varsayılan davranıştır. Diğer işaretçilerin veya temel harita etiketlerinin gösterilip gösterilmeyeceğini etkilemez.
GMSCollisionBehaviorOptionalAndHidesLowerPriority: İşaretçiyi yalnızca diğer işaretçilerle çakışmıyorsa gösterin. Bu türden iki işaretçi çakışırsa daha yüksek zIndex değerine sahip olan gösterilir. Aynı zIndex öğesine sahiplerse dikey ekran konumu daha altta olan gösterilir.
GMSCollisionBehaviorRequiredAndHidesOptional: Çakışma olup olmadığına bakılmaksızın işaretçiyi her zaman göster ve GMSCollisionBehaviorOptionalAndHidesLowerPriority öğelerini gizle. İşaretçiyi yalnızca diğer işaretçilerle çakışmıyorsa gösterin. GMSCollisionBehaviorRequired değil. Bu türden iki işaretçi çakışırsa daha yüksek zIndex değerine sahip olan gösterilir. Aynı zIndex değerine sahip işaretçiler için çakışma kuralları tanımlanmamıştır.
