Visualized LineTrace (mini library)

[Jekyll Grim Payne]

A mini-library / example that adds functions to draw a series of particles between two coordinates, and a version of LineTrace() that is visualized with those particles.
https://github.com/jekyllgrim/Visual-Li ... zscript.zs

The functions are static, contained within the JGP_VisualTrace.

Code: Select all

FireVisualTracer(Actor originator, double dist, int flags = 0, double partDist = 1, int partTics = 1, color partColor = color("00FF00"))

Fires a LineTrace from the originator and draws particle along its length. Parameters:

• originator — the actor the trace originates from. If it's a PlayerPawn, it'll fire fire from its eye height (matching the position of its crosshair), otherwise fires from actor center.
• dist — the distance of the trace
• flags — same flags as LineTrace() uses
• partDist — distance between particles
• partTics — how long the particles should exist
• partColor — the color of the particles.

Code: Select all

DrawParticlesBetweenPoints(vector3 startpos, vector3 endpos, double partDist = 1, int partTics = 1, color partColor = color("00FF00"), int flags = SPF_FULLBRIGHT|SPF_NOTIMEFREEZE)

Draws a line of particles between two points. FireVisualTracer utilizes this function. Parameters:

• startpos — coordinates of the first point
• endpos — coordinates of the last point
• partDist — distance between particles
• partTics — how long the particles should exist
• partColor — the color of the particles.
• flags — same flags as A_SpawnParticle uses. SPF_FULLBRIGHT and SPF_NOTIMEFREEZE are enabled by default.

Comes with two examples: JGP_TraceFromFace (an item that will fire a linetrace in the direction its owner is looking) and JGP_ZombiemanWithTrace (a Zombieman that constantly fires a trace wherever it's aiming).

Well shit, I needed this!

Ah, and I just spent my afternoon writing something similar

Ok, I got the latest from GitHub, spawned a few zombies, watched them walking around looking for me, killed one, then got a div by 0 crash: line 52 from 35 from 111
