wasm:

rustup target add wasm32-unknown-unknown
cargo build --target wasm32-unknown-unknown -p <proj>

wasm release:

cargo +nightly build --target wasm32-unknown-unknown -p <proj> -Z build-std=panic_abort,std

(this allows full simd instructions)

symbolic link the wasm build dir to the config dir mod dir:

cargo watch -x "build --target wasm32-unknown-unknown -p <proj> --release" -s "cp target/wasm32-unknown-unknown/release/<name>.wasm ~/.config/ddnet/mods/ui/wasm/wasm.wasm"

Windows:

cargo watch -x "build --target wasm32-unknown-unknown -p <proj> --release" -s "xcopy target\wasm32-unknown-unknown\release\<name>.wasm $env:AppData\DDNet\config\mods\ui\wasm\wasm.wasm /Y"

if cargo watch is slow (some versions are broken): watchexec/cargo-watch#276 cargo install cargo-watch --locked --version 8.1.2

Android:

# tree
ANDROID_NDK_HOME=/home/jupeyy/Android/Sdk/ndk/26.3.11579264/ cargo ndk -t arm64-v8a tree --no-default-features

# build, (currently needs hack, remove line `default = ["legacy"]` in Cargo.toml)
x build --arch arm64 --platform android --format apk -p ddnet-playground --features bundled_data_dir

x11 mouse cursor while debugging: install xdotool package if you use the vscode workspace in other/vscode it will do the following steps automatically

lldb has to execute this add start of debugging:

command source ${env:HOME}/.lldbinit

in ~/.lldbinit:

target stop-hook add --one-liner "command script import  ~/lldbinit.py"
``

in ~/lldbinit.py (no dot!):

#!/usr/bin/python import os

print("Breakpoint hit!") os.system("setxkbmap -option grab:break_actions") os.system("xdotool key XF86Ungrab")
