<aside> ⚡ script "core_predicthome" (int spd, int ptr, int timeOffs)

</aside>

Usage

This script sets the pitch and angle of the calling projectile to predict the given pointer's position, essentially leading its aim towards that pointer, taking into account distance and speed.

Parameters

• spd: int - The speed of the projectile
• ptr: int - The actor pointer to aim towards
• timeOffs: int - An optional time offset in tics to take into account for prediction.

Example

Below is a fairly accurate Magnet Missile that only redirects a single time.

actor LoreAccurate_MagnetMissile : BasicProjectile
{
	Radius 8
	Height 5
	damagetype "MagnetMissile"
	Obituary "$OB_MAGNETMISSILE"
	damage (20)
	speed 47
	+SEEKERMISSILE
	+SCREENSEEKER
	var int user_speed;
	States
	{
		Spawn:
			MAGG A 0
			MAGG A 0 A_SetUserVar(user_speed, 47)
			MAGG A 0 ACS_NamedExecuteWithResult("core_SetVelPitch",0,0)
			MAGG A 8
		SpawnLoop:
			MAGG A 0 A_SeekerMissile (0, 0, SMF_LOOK|SMF_PRECISE, 256, 10)
			MAGG A 1 A_JumpIfTargetInLOS("SpawnChase", 0, JLOSF_PROJECTILE)

		SpawnChase:
			MAGG A 0 A_Stop
			MAGG A 0 ACS_NamedExecuteWithResult("core_predicthome", user_speed, AAPTR_TRACER, 10)
			MAGG A 10
			TNT1 A 0 A_SpawnItemEx("ExplosionEffect1", 0, 0, 0, 0, 0, 0, 0, SXF_TRANSFERTRANSLATION)
		ChaseLoop:

			MAGG A 2

		Death:
			TNT1 A 0 A_SpawnItemEx("ExplosionEffect1", 0, 0, 0, 0, 0, 0, 0, SXF_TRANSFERTRANSLATION)
			stop
