Push object away from explosion center with tForm

im struggling with tFormVector and tFormPoint

TFormPoint  EntityX(lpTank\lpModel),EntityY(lpTank\lpModel),EntityZ(lpTank\lpModel),  lpTank\lpModel, lpExploded\lpModel
						
tfx# = TFormedX()*speed#
tfy# = TFormedX()*speed#
tfz# = TFormedZ()*speed#
						
						
MoveEntity lpTank\lpModel,tfx,0,tfz

what i want is the object to move away from the explosion!

i cant seem to get this right, i've tried TranslateEntity, and moveEntity, tForm and otehr algorythms, trouble is, i've done this before but i cant for the life of me remember HOW i did it! (lost my code due crashed HD)

what is speed? just to make sure its not 0 :-)

speed is the distance, i want the impact of this explosion to be lesser the further away it is

You don't need TForm to find the vector from the explosion to the tank:

vx# = EntityX(tank,1) - EntityX(explosion,1)
vz# = EntityZ(tank,1) - EntityZ(explosion,1)

This is just the 2D XZ vector as it seems from your code that you're not interested in the Y component.

what about the impacted speed?
the further away from the explosion the effect of the blast shouldn't be so great?

Off the top of my head and not tested, something like this?

ent_dist# = Abs(EntityDistance(tank,explosion))
If ent_dist# <= BLAST_RADIUS
	vx# = EntityX(tank,1) - EntityX(explosion,1)
	vz# = EntityZ(tank,1) - EntityZ(explosion,1)
	dist# = Sqr(vx * vx + vz * vz)
	nx# = vx# / dist#
	nz# = vz# / dist#
	
	bs# = BLAST_SPEED - (BLAST_SPEED * (ent_dist# / BLAST_RADIUS))
	blast_x# = nx# * bs#
	blast_z# = nz# * bs#
	
	TranslateEntity tank,blast_x#,0,blast_z#
EndIf

thanks loads big10p :)

i've sorta used something like this

tfx# = EntityX(lpTank\lpModel) - EntityX(lpProxy\lpModel)
						tfz# = EntityZ(lpTank\lpModel) - EntityZ(lpProxy\lpModel)
			
						dist# = (EntityDistance(lpProxy\lpModel, lpTank\lpModel))
			
						tfx=(tfx/(dist*dist)* 1000)
						tfz=(tfz/(dist*dist)* 1000)
						
						;MoveEntity lpTank\lpModel,tfx,0,tfz
						lpTank\lDisplaceX# = tfx
						lpTank\lDisplaceZ# = tfz

works for what i need :)

thanks again tho guys :)
