Resetting Entitys At The Start Of Every Round

By Egir Helgrimson

Introduction

Sometimes you will run into the problem of an entity that isn't reset when a new round starts. This tutorial will show an example of how to use a func_door and a multimanager to fix this.

Setup

Given that you have already made the following:

env_sprite	Name	fire
	Render Mode	Texture
	FX Amount	0
	Sprite Name	sprites/flame2.spr
	Set flag "Start on"
func_bomb_target	Target	render_fire_visible
env_render	Name	render_fire_visible
	Target	fire
	Render Mode	Additive
	FX Amount	200

This setup will make some fire visible when the bomb blows. To go into further details the fire is an env_sprite which looks like fire. The func_bomb_target is the standard entity for marking bomb sites. When the bomb is blown the target of this entity is triggered. Here the target is "render_fire_visible", which is the name of an env_render. Env_renders are used to change the rendermode of other entities. It is verry usefull for making sprites visible and invisible again. For more information about env_render, visit the VERC Collective at

When the env_render is triggered it will change the rendermode of the env_sprite such that the sprite becomes visible, e.g. starting the fire.

The Problem

When the round restarts the fire is still on and its not supose to be. In other words, the env_sprite kept its rendermode from the one given to it by the env_render, even though that was in the last round. This is an example of entities that does not reset each time a new round starts.

The Solution

Put out the fire when each round starts by rendering it invisible again with the following entity:

env_render	Name	render_fire_invisible
	Target	fire
	Render Mode	Texture
	FX Amount	0

In Half-life not all entities are reset every round. But luckily func_doors are, so we are going to use a func_door to create an event that we can react on upon round start. You might have more than one entity that needs to be reset like this, so we will make a multimanager to handle that.

Here is what the func_door and multi_manager looks like

func_door	Target	reset_manager
multi_manager	Name	reset_manager
	render_fire_invisible	0.1
	<entity_i>	0.1

Should you have other entities you want to reset; enter them in place of <entity_i> if not, just leave that field blank.

Note

To add extra (key,value)'s to a multi_manager you will need to use the SmartEdit button. For more information please see this tutorial on the multimanager: http://www.egir.dk/index.php?page=vhe_multi_manager.htm

Conclusion

This should be it. At every new round, Halflife will touch the door, to make sure that its closed, and therefore the door will trigger the multimanager, that again will trigger each of the entities that you listed in it, resetting whatever you intended to, or actually just triggering something upon every round start.
