import gameserver.model.templates.WorldMapTemplate;
import gameserver.skill.model.Skill;

public class SkillRestriction {
    private static final int RESTRICTED_MAP_ID = 1234; // restricted map id
    private static final int RESTRICTED_SKILL_ID = 5678; // restricted skill id

    public static boolean canUseSkill(Player player, SkillTemplate skillTemplate) {
        WorldMapTemplate currentMap = player.getWorldMapInstance().getWorldMapTemplate();
        int currentMapId = currentMap.getMapId();

        if (currentMapId == RESTRICTED_MAP_ID && skillTemplate.getSkillId() == RESTRICTED_SKILL_ID) {
            // Prevents use of Restricted Skill on Restricted Map
            return false;
        }

        
        return true;
    }
}
