From exploding toxic barrels in Doom to causing tactical chain reactions in Divinity Original Sin 2 explosions are among gaming’s most satisfying effects. They can also be a developmental headache. Word Explosion is a push-your-luck game with a nice ramp up in risk and reward. Creative combinations of explosives, interesting levels and a beautiful cartoon aesthetic make this game a treat.
Visuals
Using the latest hardware, modern day video games can display photorealistic worlds and artificial characters. The next generation of consoles supports up to 12 teraflops of power and 120 FPS allowing game developers to push the visual boundaries of their games.
One of the first major advances was achieving the look of in-game explosions. The circle enlarges rapidly and the particle effects shoot out in an impressive barrage of flame, sparks and smoke. The sandbox action game Just Cause series took this to the next level with a fully destructible environment and spectacular looking بهترین سایت بازی انفجار. The blazes of kerosene that fill the sky and linger in the air are breathtaking and encourage players to find new ways to blow things up.
In order to create the effect of an explosion it is necessary to add a new Emitter with the type “Flame/Smoke”. The flame sprites start off orange and quickly fade to black. The effect is created by a combination of a Bloom and a Chromatic Aberration Effect, the former affecting the brightness of an image and the latter changing the color palette based on the amount of bloom in the scene.
Sounds
Explosions in videogames are more than cool visual effects; they tend to influence everything around them. As a result, their design requires the collaboration of multiple teams with different skillsets. Besides being tied to the game’s physics system, they also need to be synchronised with their visual counterpart and balanced so that they appear to come from the right location. This is where audio engineers step in.
They usually start by recording a series of sounds that represent the attack, decay, and sustain. They then combine them into a single loop that is played at the correct volume when the explosion occurs. In this episode of his YouTube series Waveform, sound designer Marshall McGee explains how explosion sounds are made. He also challenges viewers to make their own using only their iPhone and household items.
Controls
An explosion isn’t just a visual effect; it also has a physical and damage component that impacts the world around it. The result is a complex and highly dynamic interaction of simulation, script and art that must be crafted with great care to ensure it looks realistic and feels satisfying when triggered by the player. The particle graphics you use play a huge role in how the player “reads” an explosion. A sharp burst of small, separately recognisable flames suggest burning pieces thrown out from the impact while a smooth blob of bigger particles suggests an expanding fireball.
An explosion can be configured to destroy terrain or leave a crater as well as the default option to break blocks. In addition to this, the explosion can be configured to damage or not destroy entities, such as mobs and other players, by changing its Explosion.DestroyJointRadiusPercent property. By default this is set to 0 so that grenades will not kill mobs, however it can be changed.
Damage
A keg of gunpowder explodes in a 10 ft radius dealing 7d6 fire damage, half of which is negated on a successful DC 12 Dexterity saving throw. This is a lot of damage for an explosion. The blockmap code that damages objects during an explosion is non-reentrant, so if you have multiple explosions that are causing each other directly within the same gametic (and even within the same function), they will interfere with each other’s damage, location, and blockmap iteration properties. This is a bad thing.
However, if the entity is not yet solid and has not been hit by another explosion, it will take less damage because the line trace will not have intersected the block map from where the original explosion happened. This is known as nuking, and we’ll cover it in detail later. Also, the blast radius of an explosion is different than its effect on blocks.
More Words
Explosion games are visually and physically intense. They’re often a combination of animation and particle simulation. Unlike with 3D, there’s no built-in method for adding an explosion force to 2D objects that will automatically affect physics objects. To do this, we need to get a reference to each object in the blast radius and apply a force to them individually.
