speed var doesn't do anything
im also getting this error
E 0:00:01:0214 _process: Index p_frame = 32 is out of bounds (int64_t(vframes) * hframes = 32).

while hframes is 4
and vframes is 8 ,

@export var v = 0
@export var speed = 1.0

frame += 1 * speed
else:

spacecloud ive just copied the assets to the other project and its dependencies for now
im trying to scroll thru a sprite sheet thru code which i will place on a mesh
i have no clue on how to make it work
its 4*8
so im adjusting the UV offset of the material.
how do i sample thru each row?
@export var speed = 0.1
@export var scaleU = 0.25
@export var scaleV = 0.125
var myMat = Material
var uvscale = Vector3.ZERO
var uvoffset = Vector3.ZERO
var offsetU = 0.0
var offsetV = 0.0
var time = 0.0
func _ready():
myMat = self.get_active_material(0)
uvscale = Vector3(scaleU,scaleV,1.0)
myMat.set_uv1_scale(uvscale)
uvoffset = Vector3(0.0,0.0,0.0)
myMat.set_uv1_offset(uvoffset)
offsetV = 0.0
func _process(delta):
time += delta
if time > speed:
offsetU += scaleU
offsetV += scaleV
time = 0.0
uvoffset = Vector3(offsetU,offsetV,0.0)
myMat.set_uv1_offset(uvoffset)
`is this right?

}spacecloud tnx for your time !
but i'm trying to animate a texture thru uv offset on a custom mesh , i cant use frames.
i first thought using a sprite3d was a good idea but then i needed to disabled culling which is bad for performance . and also using the uv offset lets me use custom curved meshed etc.
so i currently have a blood splat fx texture sheet thats 4* 8(32 frames) . so offset x should be 0.25 and offset y should be 0.125. im trying to figure out on how to iterate thru the whole sprite sheet by time using the offset of the spatial material.
made it work
heres' the script in case someone wants to do the same
@export var speed = 0.1
@export var framesH = 4.0
@export var framesV = 8.0
var myMat = Material
var uvscale = Vector3.ZERO
var uvoffset = Vector3.ZERO
var offsetU = 0.0
var offsetV = 0.0
var time = 0.0
func _ready():
myMat = self.get_active_material(0)
uvscale = Vector3(1.0/framesH,1.0/framesV,1.0)
myMat.set_uv1_scale(uvscale)
uvoffset = Vector3(0.0,0.0,0.0)
myMat.set_uv1_offset(uvoffset)
offsetV = 0.0
func _process(delta):
time += delta
if time > speed :
time = 0.0
offsetU += 1.0/framesH
if offsetU == 1.0:
shiftrow()
if offsetV == 1 and offsetU == 1:
queue_free()
offsetU = 0.0
uvoffset = Vector3(offsetU,offsetV,0.0)
myMat.set_uv1_offset(uvoffset)
func shiftrow():
offsetV += 1.0/framesV
