I have a spawner script which generates objects (let’s say tall pillars) and is able to generate them in random scale provided Min and Max scale values, and here’s a few lines of code controlling if I want to preserve Ratio of this random scaling or not. The problem is if I turn on Preserve Ratio ON it produces Tall and Short pillars, scaling them uniformly along all axis. But I want them to stay same height on Z axis and differ only in thickness (XY axis). So when I turn Preserve Ratio Off, it produces pillars squashed in XY which is due to the fact that X gets some random value let’s say 8 while Y gets 16. What I;m struggling with - how do I make those XY axis to produce same (uniform) values?
I know, but… probably the model was rotated/oriented and exported this way…
Nope, across XY only, but I want random value of X to be same for random value of Y. So I don’t get horizontally squashed pillars. Any way of doing it?
Ooh. Well slight problem is that I don’t know your whole spawning code.
first example: you want X and Y to receive the same random value with different Z. This will make each pillar have different X and Y scale values, but X and Y of each pillar will be the same values.
Vector3 newScale;
if (!PreserveRatio)
{
//creating a random that we will use for X and Y
float someReusableRandom = UnityEngine.Random.Range ((MinimumSize.x+MaximumSize.y)/2, (MinimumSize.x+MaximumSize.y)/2);
//assing new scale with same X and Y arguments and random Z
newScale = new Vector3 (someReusableRandom, someReusableRandom, UnityEngine.Random.Range (MinimumSize.z, MaximumSize.z));
}
else
{
newScale = Vector3.one * UnityEngine.Random.Range (MinimumSize.x, MaximumSize.x);
}
nextGameObject.transform.localScale = newScale;
If you want ALL pillars that you spawn to have the same random X and Y values, you’ll need to define that float globally and assign it on Start().
//creating a random that we will use for X and Y
float someReusableRandom;
void Start(){
...
//assigning the random value that will be the same for the lifetime of this monobehaviour
float someReusableRandom = UnityEngine.Random.Range ((MinimumSize.x+MaximumSize.y)/2, (MinimumSize.x+MaximumSize.y)/2);
...
}
void nextPillar(...){
...
Vector3 newScale;
if (!PreserveRatio)
{
//assing new scale with same global X and Y arguments and random Z
newScale = new Vector3 (someReusableRandom, someReusableRandom, UnityEngine.Random.Range (MinimumSize.z, MaximumSize.z));
}
else
{
newScale = Vector3.one * UnityEngine.Random.Range (MinimumSize.x, MaximumSize.x);
}
nextGameObject.transform.localScale = newScale;
...
}
Thanks a lot FMark92, but unfortunately it didn’t work for some reason, though reading your code it should have been working precisely the way I wanted… That’s what I did:
/// if set to true, the random size will preserve the original's aspect ratio on all three axis
public bool PreserveRatio=false;
/// if set to true, some random number will be generated along X and Y only and preserving their aspect ratio. Z will be random
public bool PreserveRatioXY=false;
/// we rescale the object according to first uniform scaling method
Vector3 newScale;
if (!PreserveRatio)
{
newScale = new Vector3 (UnityEngine.Random.Range (MinimumSize.x, MaximumSize.x), UnityEngine.Random.Range (MinimumSize.y, MaximumSize.y), UnityEngine.Random.Range (MinimumSize.z, MaximumSize.z));
}
else
{
newScale = Vector3.one * UnityEngine.Random.Range (MinimumSize.x, MaximumSize.x);
}
nextGameObject.transform.localScale = newScale;
/// we rescale the object according to second non-uniform scaling method
Vector3 newScaleXY;
if (!PreserveRatioXY)
{
//creating a random that we will use for X and Y
float someReusableRandom = UnityEngine.Random.Range ((MinimumSize.x+MaximumSize.y)/2, (MinimumSize.x+MaximumSize.y)/2);
//assing new scale with same X and Y arguments and random Z
newScaleXY = new Vector3 (someReusableRandom, someReusableRandom, UnityEngine.Random.Range (MinimumSize.z, MaximumSize.z));
}
else
{
newScale = Vector3.one * UnityEngine.Random.Range (MinimumSize.x, MaximumSize.x);
}
nextGameObject.transform.localScale = newScaleXY;
Could you please show exactly how these code strings would look with my example?
