step3d_model(3)

✨ NAME ✨

step3d_model — move forwards and sidewards, bestie 💅

This page is step3d_model(3) from the Arcan Lua API, and it's giving "one function, two movement moods, zero cap" energy 🫶

🌸 SYNOPSIS 🌸

       float:x, float:y, float:z
       step3d_model( vid:model float:fwd, float:side )
       step3d_model( vid:model float:fwd, float:side, uint:time=0 )
       step3d_model( vid:model float:fwd, float:side, uint:time,
       bool:update=true )
       step3d_model( vid:model float:fwd, float:side, uint:time, bool:update,
       bool:mask_x=false )
       step3d_model( vid:model float:fwd, float:side, uint:time, bool:update,
       bool:mask_x, bool:mask_y=false )
       step3d_model( vid:model float:fwd, float:side, uint:time, bool:update,
       bool:mask_x, bool:mask_y, bool:mask_z=false )
       step3d_model( vid:model float:fwd, float:side, uint:time, bool:update,
       bool:mask_x, bool:mask_y, bool:mask_z, uint:interp=INTERP_LINEAR )

🔥 DESCRIPTION 🔥

Okay so step3d_model is literally the movement combo platter: it combines the movement behavior of forward3d_model and strafe3d_model into one call. The whole point? Better scheduling of motion sequences, and being able to evaluate what a transformation would do without applying it when the optional update argument is set to false. That's the main-character detail, no cap 😭

the little cast 💅

• vid:model — the model you're moving.
• float:fwd — the forwards amount.
• float:side — the sidewards amount.
• uint:time=0 — optional time value, defaulting to 0.
• bool:update=true — optional, defaulting to true; when it's false, the transformation's consequences get evaluated without being applied.
• bool:mask_x=false — optional, defaulting to false.
• bool:mask_y=false — optional, defaulting to false.
• bool:mask_z=false — optional, defaulting to false.
• uint:interp=INTERP_LINEAR — optional interpolation value, defaulting to INTERP_LINEAR.

And it returns float:x, float:y, float:z, so you get the coordinates back, bestie 🎀

The update default is true; flip it to false only when you want the evaluate-without-applying behavior. That's the vibe check, periodt.
