  • Hi,

    I'm looking for a way to make procedurally growing tree for my game, but I don't know how to go about it. Any suggestions?



  • Try Construct 3

  • If you don't want to use up a lot of sprites, you will probably paste sprites to the canvas/paster plugin or draw paths with those (not sure about the paster plugin, has been too long since I've used it).

    As to the tree itself, think about:

    • branching of one line into 2 or more at a splitting angle.
    • a max. amount of branching allowed.
    • number of branches per split
    • Line lengths (stem is longest, little branches the shortes)
    • will it get thinner each branch or continually? continually will be more coding work
    • add randomness (lengths, angles, thickness, the possibility for a branch to end before the branch amount maximum)
    • leaf "branches" after x-th branch level?

    Well, I guess it depends on how complex you want to go into this matter and what effect you want to achieve exactly with this.
