Level door text

[Datguy5]

Hello!
How do i make a text appear in the screen when the player looks at a level door? Here is my script file:
////////////////////////////
// Run when the map starts
void OnStart()
{
AddUseItemCallback("", "Khii", "Lockedd", "KeyOnDoor", true);
SetEntityCallbackFunc("Khii", "OnPickup");
AddEntityCollideCallback("Player", "FlyingJesus_1", "HolyJesus", true, 1);
AddEntityCollideCallback("Jesus1", "FlyingJesus_1", "Sound", true, 1);
AddEntityCollideCallback("Player", "Closett", "Monstar", true, 1);
AddEntityCollideCallback("Player", "Slam1", "func_slam", true, 1);
SetEntityCallbackFunc("Avain", "OnPickup");
}

void HolyJesus(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("Jesus1", true);
AddPropForce("Jesus1", 0, 0, 20000, "World");
}

void Sound(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("", "24_iron_maiden.snt", "FlyingJesus_1", 0, false);
}

void OnPickup(string &in asEntity, string &in type)
{
SetEntityActive("grunt_1", true);
GiveSanityDamage(10.0f, true);
AddEnemyPatrolNode("grunt_1", "PathNodeArea_1", 2, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_2", 1, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_3", 1, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_4", 1, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_5", 1, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_6", 1, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_7", 1, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_8", 2, "");
AddEnemyPatrolNode("grunt_1", "PathNodeArea_9", 1, "");
}

void func_slam(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("Slammer", true, true);
PlaySoundAtEntity("", "react_breath_slow.snt", "Player", 0, false);
PlaySoundAtEntity("", "react_scare", "Player", 0, false);
PlaySoundAtEntity("", "close_door.snt", "Player", 0, false);
GiveSanityDamage(10.0f, true);
}

void Monstar(string &in asParent, string &in asChild, int alState)
{
SetEntityActive("Closet", true);
}

void KeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("Lockedd", false, true);
PlaySoundAtEntity("", "unlock_door", "Lockedd", 0, false);
RemoveItem("Khii");
}
