Zoom Camera with Enemy tagging

How to create a zoom camera/binoculars for enemy tagging

 

In Far Cry 4 you have a camera which you can use to zoom in on your enemies or prey and tag them with a visible symbol so that they are easier to spot. In Ghost Recon you have binoculars that can tag enemies. This tutorial is to create something similar.

Controls for the player:

D pad up to turn camera on and off

Left and right triggers to zoom in and out

D pad to turn left and right

Enemies will be automatically tagged when in range.

 

Instructions

In your enemy brains

WHEN [boolvar: seen] DO [display][icon:Direction arrow][above]

You can use whatever tagging symbol you like – and can use different ones for different enemies.

Your player

Attach a camera gizmo in front of his head. This will be your starting point for the camera.

In the player brain

WHEN [Dpad][up direction][pressed] DO [toggle][boolvar:camera]
WHEN [boolvar:camera]
…WHEN DO [display][Peephole small][screen center][scale][35][color:0001 (black)]
…WHEN [started to] DO
…/…WHEN DO [objvar:cam][=][create][IWP:zoom camera][at position][IWP:camera gizmo][position]
WHEN [not][camera]
…WHEN [1st person][from socket][center] // optional (I changed this as fighting close up you could not see the enemy)
…WHEN DO [display meter][health][screen top left]

…as childlines add all your normal controls here so that the player cannot move or interact when the camera is active.

Create a logic cube or camera gizmo to house the camera brain, make it a template. Turn on the see sensor and adjust it to the size you require for the camera to detect enemies. Change the properties to make the camera Team 2 (this will prevent the enemies attacking the camera when you get close).

Zoom camera brain

Page 1 – This controls the zoom and the enemy targeting

WHEN [started to] DO [forward][=][IWP:your player][forward]
WHEN DO [call page][2]

 

This will mark the enemies in Team 2 when seen by the camera.

WHEN [for each of][allies] DO
…WHEN [see][it]
…/…WHEN [not][it][boolvar:seen] DO [it][boolvar:seen][=][true]
…/…/…WHEN [started to] DO [play sound][UI Basic Toggle]

 

This controls the zoom

WHEN [Right trigger][and][numvar:zoom][<][15]
…WHEN DO [move][object forward]
…WHEN DO [numvar:zoom][increment by][0.1]
WHEN [left trigger][and][numvar:zoom][>][1] DO [move][object backward]
…WHEN DO [numvar:zoom][decrement by][0.1]

This destroys the camera when the player turns it off

WHEN [dpad][up direction][pressed] DO [destroy][me]

 

page 2 – this controls the left and right turns of the camera

WHEN DO [1st person camera][without controls]
WHEN DO [numvar:look left][=][clamp][max][30][min][-30][numvar:look left]
WHEN DO  [numvar:look right][=][clamp][max][30][min][-30][numvar:look right]
WHEN [Dpad][left direction]
…WHEN [numvar:look left][not equal to][30] DO [yaw][slowly][camera relative][(][right][)]
…WHEN DO [numvar:look left][increment by][1]
…WHEN DO [numvar:look right][decrement by][1]
WHEN [Dpad][right direction]
…WHEN [numvar:look right][not equal to][30] DO [yaw][slowly][camera relative][(][left][)]
…WHEN DO [numvar:look right][increment by][1]
…WHEN DO [numvar:look left][decrement by][1]
