I'm super stoked about this one as it took a lot of scripting to get it work, but the effect is cool.
Push Monster
An air magic spell.. currently level 0 with a mana cost of 20 and two runes. Feel free to tweak it how you want.
The basic idea is that the monster directly in front of you is teleported one space away from the party in the same direction. This gives you enough time to either close a door, or sneak forward and potentially get out of a dead end. Because of the complex nature of the spell I have built it up using functions, so there is a minimal amount to put in spells.lua, a script_entity that needs placing in the editor and a custom monster to add to monsters.lua.
spells.lua

Optional Particle Effect
To use the optional particle effect you will need to uncomment the 3 lines relating to spawn FX in the script above and add the following to a
particles.lua file
Code: Select all
defineParticleSystem{
name = "push_spell",
emitters = {
{
spawnBurst = true,
maxParticles = 40,
sprayAngle = {0,100},
velocity = {0.8,2},
objectSpace = false,
texture = "assets/textures/particles/smoke_01.tga",
lifetime = {0.3,1},
color0 = {0.8, 0.9, 1.8},
opacity = 0.3,
fadeIn = 0.1,
fadeOut = 0.3,
size = {0.4, 0.7},
gravity = {0,0,0},
airResistance = 2,
rotationSpeed = 2,
blendMode = "Translucent",
},
-- glow
{
spawnBurst = true,
emissionRate = 1,
emissionTime = 0,
maxParticles = 1,
boxMin = {0,0,-0.1},
boxMax = {0,0,-0.1},
sprayAngle = {0,30},
velocity = {0,0},
texture = "assets/textures/particles/glow.tga",
lifetime = {0.5, 0.5},
colorAnimation = false,
color0 = {1.0, 1.0, 1.8},
opacity = 0.5,
fadeIn = 0.01,
fadeOut = 0.5,
size = {1, 1},
gravity = {0,0,0},
airResistance = 1,
rotationSpeed = 2,
blendMode = "Additive",
}
}
}
Make sure that you include an IMPORT for your particles.lua file in the
init.lua file
